Hot weather is tough on pollinators. 🐝 I designed this Bee & Bumblebee Watering Station to provide a safe place for bees, bumblebees, butterflies, and other beneficial insects to drink without risking drowning. The concentric ribbed rings create shallow water zones and secure landing surfaces. Place it near flowering plants and help your local pollinators stay hydrated throughout the season. 🌸💧🐝

Got a STIHL HSA 26? Now you can use it to power Sarlix's excellent grass spreader. This adapter replaces the Bosch ISIO interface with a STIHL HSA 26 mount and includes a dedicated drive shaft and mounting plate. A great way to reuse an existing tool and expand its functionality. Feedback and improvement ideas are welcome!

My **Apple Mac mini M4/M4 Pro Wall Mount** is live! Designed to keep your Mac mini secure, planted, and off the desk. Great for clean setups, behind monitors, or tight workspaces.

I made a vacuum robot ramp for LIDL child safety gates and wanted to share it in case it helps. It fits gates with a 30 mm bottom bar, is 29 mm high, 600 mm wide, and prints in 3 parts. Optional 10 x 5 mm press-fit magnets keep it secure on the gate while still allowing easy removal. Tested with a Roborock, and my print also held 150 kg.

I designed this STIHL AS 2 battery mount because the existing options I found did not match my requirements for fit, strength, and practical everyday use. My goal was to create something rugged, functional, and reliable rather than just another generic holder. I’m starting with multiple variants, including a wall-mounted version with screw slots and a stand-alone version, and I plan to add more over time. Feedback is welcome, especially on which variant you’d like to see next.

Designed to solve a simple problem: standard IBC adapters blocked my tank’s original closing mechanism. This one avoids that, keeps the closure usable, and now includes a 10 mm longer version plus a TPU inner seal.

New model published: Gardena Micro-Drip 13 mm ground spike holder. I couldn’t find an existing design that matched my use case, so I made a sturdier print-in-place PETG version. It includes 5 variants with toothed, smooth, and partial-teeth options in 160 mm and 180 mm lengths, measured from the tube center to the spike end. Built for practical use, outdoor durability, and better fit.

Just uploaded a Stihl AP battery slot dust cover. It plugs the battery bay during storage (battery removed) to keep dust off the contacts. Main reason I made it: you can customize it—add your tool name/ID and tweak the cover instead of buying a fixed off-the-shelf solution. If you print it, tell me how the fit is on your tool and what material you used. 🙌

Update: I added 2 new print profiles and a new design variant with pin holes to help keep the crown in place. This version includes left + right Czech lions that can be used as hair pins—slide them through the holes and into the hair to secure the crown on the head for play or cosplay.

I just published a Czech Lion Hairpin designed for actual wear, with three versions: short / medium / long pin legs so you can pick the hold that fits your hair and style (fine hair + half-up → short, everyday → medium, thick hair + full bun → long). If you print it, I’d love to see your makes—please mention which length you used (S/M/L) and what filament worked best for you.

iFixit’s Anti-Clamp is awesome… but it deserves a proper case. So I made a magnetic box that’s workshop-proof and easy to toss in a bag. Specs: 8× Ø6×1.6 mm press-fit magnets. Try it and tell me: should the next version include a logo cutout, nameplate, or stackable latch? If this is useful, hit Boost — it directly supports more practical tool storage designs.

iFixit ships a great case for their screwdriver + bits, but the multimeter doesn’t get the same protection—so I designed one. This is a 2-part magnetic box that stores the iFixit multimeter (and keeps the leads/plugs together) in a closed case. Magnets: 8× 6×1.6 mm, held in hex press-fit pockets (no adhesive). Feedback wanted: do you prefer a tighter snap (stronger magnets) or easier one-hand opening?

Fixed our ETA sandwich maker with a new replacement clip. The original snapped and I couldn’t find the right spare, so I modeled a sturdier version and optimized it for ASA (tough + better heat tolerance than PLA). If you print it, please share your ETA model number and feedback on fit—photos welcome. Happy to iterate!

Gridfinity 5×5 insert sized to fit the Bambu Lab P1S build plate, so it prints in one piece and drops into standard 5×5 bins. Holds a Milwaukee M12 rotary tool + 1 battery, with dedicated slots for bits and the small tools you need for swapping/adjusting. Feedback welcome! #Gridfinity #BambuLabP1S #MilwaukeeM12 #RotaryTool #FunctionalPrint

New upload: a simple foldable phone stand that supports portrait + landscape and quick rotation between the two—made for travel. Fit notes: Designed around a Dbrand case and specifically for the Anker Zolo MagSafe/Qi puck. The puck intentionally sticks out (not a tolerance issue). Very thick/raised-edge cases or other “similar” chargers may not fit. Charger link: https://www.amazon.de/dp/B0DRCSZ618?ref=ppx_yo2ov_dt_b_fed_asin_title

Hi MakerWorld! 👋 I just published a set of modular lantern inserts inspired by my passion for electron microscopy. They’re a small tribute to TESCAN’s microscope range: CLARA → AMBER X → TENSOR → Nanospace (UHV FIB-SEM). It was a fun build—if you’re into microscopy (or just like science-themed lighting), I hope you enjoy it. Share your makes/photos if you print it!
