LINK Download:Pallone da calcio a levitazione magnetica - Modello di stampa 3D gratuito - MakerWorld Mi sono divertito a realizzare questo progetto, cercando di unire design e tecnologia in qualcosa di semplice ma d’effetto.L’idea era quella di ricreare il momento del Goal, ma in modo diverso: un pallone sospeso grazie alla levitazione magnetica all’interno di una porta con la rete sagomata Dietro a un risultato pulito c’è stato un lavoro importante, soprattutto sulla rete, studiata per ottenere una deformazione realistica senza complicare la stampa.L’obiettivo era rendere tutto il più semplice possibile per chi lo realizza: stampa facile, assemblaggio rapido e un effetto finale che sorprende. la rete è stata creata utilizzando un metodo che ho vista sul concorso natale dove un creatore creava una sagoma per deformale la plastica. Ma la vera difficoltà è stata la realizzazione della palla da calcio. Il diametro della sfera doveva essere il più ridotto possibile, pur integrando al suo interno il magnete. Ho dovuto posizionare il magnete il più in basso possibile, così da aumentare la distanza dalla base e rendere più evidente lo spazio di fluttuazione percepito dall’occhio. Tutto quello che compone la palla da calcio:La palla è composta da tre corpi: Il pezzo SOTTO che tiene alloggiato il magneteil pezzo ANELLO che unice pezzo sopra e pezzo sotto in più spinge in basso il magnete magnete e tiene in posizione la scheda ledin fine il pezzo SOPRA con tutti i fori per poter permettere alla luce di passare più facilmentePEZZO SOTTO:PEZZO ANELLO:PEZZO SOPRA: Inoltre, le FACCETTE bianche centrali tengo ancora più saldati le due partiI pali della porta sono semplici da stampare e da assemblare, ho creato delle giunzioni semplici e veloci per l'assemblaggio Per la BASE ho pensato proprio a tutto dalla clip che blocca la schedina per il sensore touch e per migliorare l'assemblaggio ho curato il passaggio cavi creando delle piccole linguette.  In fine la targhetta creato con OpenSCAD, caricata con successo sulla piattaforma in modo tale da poterla modificare a vostro piacimento. Con la possibilità di ingrandire il testo e di modificare lo spazio fra lettere.   Ho sempre cercato di dare il massimo su questa piattaforma, e vedere che i miei progetti vengono apprezzati da così tante persone è una soddisfazione enorme. Grazie davvero per tutto il supporto che mi avete dimostrato.MC2 project 3D

So much has happened around CaseStudio since the pre-launch phase began. The response has been overwhelming, so today I want to give you an update, announce the official launch, and address your feedback directly.First, a huge thank you to our more than 1,700 followers. I never imagined CaseStudio would inspire so many people in such a short time. Your messages and discussions are massively shaping this project. Without you, CaseStudio wouldn't be where it is today, you’ve given me an incredible number of great ideas. Save the Date: Crowdfunding Campaign LaunchThe campaign starts on: Wednesday, January 14th at 4:00 PM CET (16:00)There will be limited Early Bird offers at launch. So, if you’re there from the very beginning, you’ll secure CaseStudio at the best price. STEP Export at LaunchA specific suggestion from the community was to offer STEP files to make editing and customization easier. That idea was implemented right away. STEP export is now built into the system and will be available when the website launches, giving you maximum freedom to customize and modify your designs.Update on MagSafe IntegrationBy far the most common question was: "Is MagSafe coming?" The answer: Yes, it is planned. MagSafe is set as one of the first Stretch Goals. My goal is to be able to put magnets into the backplate. As soon as we reach the goal, development begins.  The Foldables TopicTransparency is important to me: At the moment, there isn’t a perfect solution for folding smartphones yet. The TPU I use is intentionally quite firm to ensure stability and a premium feel, but this makes it unsuitable for the hinge mechanism of foldables. One idea would be a two-part design, however I’m not yet confident about how reliably the two parts would hold together while still allowing the backplate to be swapped easily. I’m continuing to test different approaches, and if you have technical ideas for a stable connection solution, I’d love to hear from you. Your Opinion CountsThe countdown is on. CaseStudio is intended as a project that grows with its community. Do you have further suggestions for improvement? Please comment on this post or message me directly. I look forward to January 14th!

LAST UPDATE Hello, MakerWorld Community!First off, a huge thank you to every single one of you. We already have over 700 watchers on the crowdfunding page!!! Honestly, I didn't expect such a response. Your trust has changed my approach: I decided not to rush a release "as is," but to seriously invest in quality and UX to live up to your expectations. Our project will not fall short of top-tier devices in this segment.Today, I’ll share details about major hardware changes, the new "heart" of the system, and our future plans.1. Visual Revolution: 4.3" IPS instead of 3.5" TFTThis is the biggest visual change. We are moving from a 480x320 resolution to a 800x480 IPS 4.3" screen. The difference in person is simply night and day. The camera doesn't fully convey the vibrancy, viewing angles, and font sharpness, but believe me—I never want to go back to the old screen.  I tested two boards with capacitive touch: the Sunton ESP32-8048s043 and the Waveshare ESP32-S3-Touch-LCD-4.3. My choice is the Waveshare. It has a more thoughtful form factor, good wiki, convenient mounts, and a smart connector layout, which is critical for our case design. However, I am still keeping Sunton in mind as an alternative.  Honest talk about the trade-offs: The Waveshare board lacks hardware PWM for smooth brightness adjustment "out of the box." However, this is a calculated compromise. Its advantages - ideal size, good wiki, smart connector layout, and price - far outweigh this limitation. We are solving the "night blindness" issue elegantly via software: I am developing a special "Dark Mode" with color inversion and a muted palette. It looks even cooler than simply lowering the brightness!  2. New LVGL Interface & Backer BonusesWith the new resolution, we need a new UI. I am rewriting the interface using the LVGL library. It will look modern, smooth, and professional. You can see the prototype in the photo.  Open Source vs. Crowdfunding:Basic Version: Fully Open Source code, clean and functional interface. Available to everyone for free.  Premium Version (for Crowdfunding participants): A special firmware version with expanded customization options (color selection, extra themes, extensions). The code for this version will also be available to you (in a private repository)—the Open Source philosophy remains! This Premium version is an exclusive reward for my backers, granting access to advanced customization features while ensuring the core project remains open and free for everyone. 3. Sensors: Switching to Sensirion SEN66During testing, I faced a reliability issue with the popular SGP41 sensor. I purchased three separate units, and one of them failed to work correctly. This highlights a major problem in the DIY world: when buying individual breakout modules, it is all too easy to run into counterfeits or components with poor quality control. I don't want you to face this lottery.A big thanks to @MobZ in the comments for the tip about the Sensirion SEN55. I studied the documentation and realized - this is the solution we need to ensure consistency. In the updated version, we will use the Sensirion SEN66. It is an new "All-in-One" module from a top-tier brand:Temperature & HumidityCO2VOC & NOx IndicesPM1.0, PM2.5, PM4.0, and PM10It is already running in my prototype, and the stability of the readings is impressive. The quality is top-notch. 4. "Heavy Artillery": Formaldehyde (HCHO)The SEN66 is beautiful, but it lacks a formaldehyde sensor (this feature is only in the SEN69C series, which isn't even on sale yet). By popular demand, I am adding optional support for the separate Sensirion SFA30 module. This is the undisputed "King" in this budget range. It is on its way to me for testing. This makes Project Aura a real desktop laboratory. The sensor will be optional - if you don't need it, you simply don't connect it.5. No-Solder AssemblyThe transition to Sensirion modules and the Waveshare board brings us closer to the main goal—No Soldering Assembly. I am 90% sure the final version can be assembled just by plugging in connectors, making it perfect for beginners—like a building block set. I will confirm this exactly once the stable final version is assembled.What's Next?Sensirion SFA30: Wiring, coding, and testing. RTC & Pressure: I ordered an external I2C Real Time Clock module (PCF8523) so data isn't lost on reboot/power loss, and high-precision barometers (DPS310 and BMP580). You will be able to connect whichever one is available to you without changing the code. More on this in the next post. Case: Due to the new 4.3" screen, the case will be completely redesigned. It's too early to talk about other case variations; I need to finish the main one first. Home Assistant: Yes, I think MQTT support will definitely be included. I understand this is critical for many of you. I haven't dived deep into it yet, but I'll try to share more in the next article.Question to the Community:I'm an engineer, not a marketer. Could you suggest which resources, forums, or subreddits would be appropriate to publish a detailed technical article about the project to attract like-minded people? I would be grateful for links and advice! Thank you for staying with the project. Follow my profile so you don't miss the new updates!

Hello, MakerWorld Community!  🔥 BREAKING NEWS: Major Hardware Upgrade!LAST UPDATE  Important: This post is the start of a conversation. I am still polishing the code and design. If you have questions about circuit design, component selection, logic, or ideas for new case designs — write in the comments, I will answer everyone! Component Status & Ongoing Testing The hardware configuration of this project is not final yet. I’m actively testing alternative ESP32 boards with IPS displays, as well as the Sensirion SEN66 sensor, which could help eliminate some common DIY issues such as complex wiring, soldering, and software setup. The goal is to find the most reliable, beginner-friendly, and long-term maintainable solution. Once the final hardware choices are locked in, I’ll publish a detailed update explaining the decision and the trade-offs involved. I am preparing to launch Project Aura — an Open Source air quality monitoring station. Before publishing the print files and firmware, I want to invite you "under the hood" of the project and share the engineering decisions behind it. In this project, I set myself an ambitious goal: to create a device with the accuracy of a professional laboratory instrument that a beginner can replicate in a single evening.Today I will tell you why I chose this specific hardware, how the firmware logic works (spoiler: there are watchdogs, ring buffers, and sprites), and why CO2 is not just numbers on a screen.1. Hardware: Why "All-in-One"?The heart of the project is the ESP32-3248S035 board (often found under brands like Sunton or LCDWiki).Many will ask: "Why a TFT screen and not a trendy IPS?" Let's be realistic. The viewing angles of the current 3.5" TFT screen are not perfect. However, this board has two killer features that outweigh the downsides:Price: The entire module (powerful dual-core ESP32 + 3.5" touchscreen + drivers) costs about $18. Simplicity: This is a "2-in-1" solution. You don't need to solder 12 wires to connect the screen and touch panel, or struggle with pinouts and libraries. Everything is already assembled at the factory.For connecting sensors, the board already has JST 4-pin (I2C) and UART connectors broken out. Effectively, assembly is reduced to plugging in ready-made modules rather than weaving a "web" of wires. A Look into the Future (IPS Version): I understand that many want a perfect picture. Right now, a similar board but with a 4.3-inch IPS screen (800x480 resolution) is on its way to me. It costs about $8-12 more. I will test it, and if the image quality justifies the price, I will adapt the interface and case for it.2. Sensors: The Dream TeamI categorically refused to use cheap analogs. Inside is "heavy artillery" from Sensirion and Bosch. Here is what each module is responsible for:CO2: Sensirion SCD41 (Switzerland)The Tech: This is a true photoacoustic NDIR sensor. It measures the resonance of carbon dioxide molecules.Why you need it: To avoid being a "zombie." At CO2 levels above 1200 ppm, the brain starts to work poorly, and drowsiness sets in. The sensor will tell you when it's time to open a window to restore productivity.In Firmware: I implemented smart smoothing (moving average of 5 samples), but with a "Jump handling" algorithm: if the CO2 level changes drastically (e.g., you breathed on the sensor), the buffer resets for an instant reaction. Pressure compensation using data from the BME280 is also used.Dust: Sensirion SPS30The Tech: Laser Scattering sensor with a high-quality fan and contamination protection for the optics (lifespan >10 years).Why you need it: It sees what the eye cannot — PM2.5 (microparticles that penetrate the blood) and PM10 (allergens, pollen). This is critically important for allergy sufferers and city dwellers.Chemistry: Sensirion SGP41The Tech: MOX sensor (Metal-Oxide) measuring VOC and NOx indices.Why you need it: This is an "artificial nose." It detects smells you might miss (fumes from new furniture, varnish, household chemicals) or combustion products (gas stove, street exhaust).Climate: Bosch BME280The Tech: The industry standard for measuring temperature, humidity, and pressure.Why you need it:Humidity: Dry air in winter kills immunity and damages skin.Pressure: Helps predict migraines for weather-sensitive people.In Firmware: The system stores a 24-hour pressure history in a ring buffer and calculates trends (3h and 24h). If the pressure drops too fast (>7 hPa/3h) — prepare for a storm or a headache.3. Firmware: Logic & UXThe firmware is written in C++ (Arduino IDE) using the TFT_eSPI library.Flicker-Free UI: I actively use Sprites. When data updates, the screen does not blink; only the changed numbers are redrawn.Two Themes: Light and Dark (switchable via the settings menu).Non-Volatile Memory: All settings (brightness, touch calibration, temperature offset) are saved in NVS (Preferences) and are not lost when powered off.Ambilight: A rear RGB LED mirrors the general air status with color (Green/Yellow/Red), so you can see the air quality even with your peripheral vision.4. Web Installer & DiagnosticsI know that installing software is the hardest part for beginners. So I removed the need to download the Arduino IDE, libraries, and drivers.You go to the project website (via Chrome/Edge).Connect the board via USB.Click one button: "Install". Done.Web Serial Monitor I also added a web-based diagnostic tool. If something doesn't work after assembly (for example, you forgot to connect a wire to the CO2 sensor) or mixed up pins, you open the console right in the browser and see a clear error message: "SCD41 not found, check wiring". This turns debugging from a torture into a simple process.Project StatusRight now, I am finishing polishing the interface and writing the documentation. The prototype is already working on my desk and looks great. I would be happy to hear your opinion in the comments: what questions about assembly do you have? What would you like to know more about in future posts? Breathe clean air!
