Multi Fidget Stim Tool System!I uploaded the Multi Fidget Stim Tool a few months back, and I have to say the response has been amazing! Thank y'all so much for all the support. When I first made the Multi Fidget Stim Tool, I expected it to be a one-off print, but the amount it has grown since then—thanks to community feedback—is incredible. It has reached a point where I feel it needs some organization and cleaning up, so I’m excited to announce that I’ve updated and expanded the Multi Fidget Stim Tool into a fully modular system that allows users to make their own custom fidget tools!For those who haven't seen my work before, the Multi Fidget Stim Tool is a design that brings several popular fidget mechanisms together into a "choose-your-own-adventure" style modular tool. It focuses on a center roller full of spikes with end caps that screw on and off to provide different sensory inputs. This system has evolved significantly and is now the Multi Fidget Stim Tool System, or MFST for short.Summary of Changes:New Collection: A central hub has been created to house all parts and prints.Separated End Caps: Caps are now in their own prints to better reflect material usage and print time.Renamed Intensity Levels: Textures have been renamed for better clarity.Alignment Engravings: Symbols added to all parts for easier assembly.New Parts: Added Stubby Rollers, a Joystick fidget end cap, and a "Techno" roller texture.Improved Geometry: Updated for smoother spinning, better keyboard switch compatibility, and higher print success.      ←---- CLICK HERE!Clearer Assembly: How it WorksThis system is made to grow. You can keep adding new ends and longer bodies to change the feel:The A & B Sides: To ensure everything fits perfectly, the parts now have two different sides.Side A parts have a Circle (○) on them. Side B parts have a Square (□) on them.Just match the shapes (Circle to Circle, Square to Square) to put it together.Splitting the End CapsAs the system grew, I realized that having every end cap and roller in the same print file was a cluttered approach. I’ve decided to split the end caps into separate files so y'all can pick and choose exactly what you want. All print profiles have been renamed to reflect the new side-naming convention, so you can clearly see what fits together. This also helps MakerWorld’s summaries reflect more accurate print times; previously, the profile was reaching 11 plates and 9 hours of printing, which isn't accurate if you only want one tool.This left the cores of the system. I didn't want every file to require other downloads just to be complete, so I’ve kept the spiked end caps with their matching rollers. This way, if someone wants to print a single spikey stim tool, they can do just that as a stand-alone print. Smooth and ridged end caps have now become the "accessories" found in the collection.New MFST CollectionAs I kept adding files, it became impossible to backlink everything to each other. I’ve made a collection to house every MFST print file. Every file has a photo with a back-link attached; if you click it, you’ll be sent to the collection where everything is clearly named. My hope is that this helps people find the end cap files more easily, but let me know if this works well for y'all!Updated GeometryI have read each comment and made changes to fix reported issues. These updates include:Brim Settings: To help users on bed-slingers whose rollers were coming off the bed, I’ve added an 8mm wide brim with a 0.2mm offset. It stays secure but comes off cleanly.Mirror-Ended Rollers: Many users wanted to attach two of the same spinner (like two ratchets). Since those both use the Side A screw, I created "Side AA" and "Side BB" rollers so you can have matching ends.Smoother Spin: I updated the geometry of the small screw so smooth-spinning end caps spin faster and longer.Button Clicker: I updated the geometry to work with most keyboard switches, including MX and Kailh styles.New Naming ConventionSince the original file was a one-off, I hadn't named it with an intensity level. The old "Normal, Medium, Extreme" naming was confusing, so I’ve switched to Low, Medium, and High. Please note: this means the old "High" and new "High" are not the same. I've also added the "Side A/B" suffix to all parts for clearer assembly.New Joystick & Stubby RollersJoystick: The most requested feature is here! This is a print-in-place file that pops off the plate and attaches immediately. It uses a Side B connection to give more function to that side of the tool.Stubby Rollers: These are single-sided, shorter rollers for a more portable option. I felt the original was a bit big for a keychain, so these are perfect for on-the-go. They come in Spikey, Ridged, and Techno textures in all intensity levels.The New Techno Texture is more of an aesthetic print that has a no-AMS multi-color aspect to it and looks great! Markets!I started working on this project last summer while selling at farmers' markets. I had a "Fidget Clicker Bar" that kids loved, so I wanted the MFST to have that same interactive element. For the sellers out there: you can print these in a bunch of colors and place them in bins for an interactive "Build-Your-Own" station. If you’re interested in selling these, please check out my membership for a commercial license.ConclusionI’ve got even more parts in testing that I'll be adding soon. All of this was thanks to the feedback and support of the community, so again—THANK Y'ALL!

If you’re a creative person like me, you’ve probably reached the point where your growing collection of markers starts taking over your desk. I kept stacking boxes and trays, but none of them really worked — too big, too small, or just not made for the tools I actually use.So I designed something better: a parametric marker stand that adjusts to exactly how many markers you own — whether it’s 12, 72, or even 288.What Makes It Different?This isn’t just a generic pen holder. It’s a fully customizable, 3D printable stand designed specifically for alcohol-based markers like Copic, Ohuhu, TouchFive, and more.You can change the number of columns (up to 36) and rows (up to 8) in the parametric model. That gives you a max of 288 markers in one clean, compact layout.It prints fast, uses very little material, and requires no supports.Designed with Function in MindEach slot is angled slightly upward for easy visibility and access. It’s compact, stackable, and you can even scale or segment the model to fit smaller printers.Want to mount it to a wall? You can. Want to keep it horizontal on your desk? That works too. Need a smaller one just for your sketching set? Done.It grows with your collection.⚠️ Important Note on SizeSome larger configurations — like the full 36×8 version — won’t fit on small build plates (like A1 mini or Prusa Mini).You can either:Split the print into parts, orChange the dimensions in the parametric file (included)There’s a version ready to print, and another for editing in Fusion 360 or OpenSCAD if you want total control.Quick Print SpecsMaterial: PLA or PETGLayer height: 0.2 mmWalls: 2–3Infill: 10–15%Supports: NoneOrientation: Base flatPrint time: From 20 minutes to 5 hours depending on layoutUse CasesArtist studiosStudent desksHobby roomsClassroom supply wallsComic/manga coloring setupsPortable kits for art conventionsFinal ThoughtsI made this to solve a real problem — organizing my marker set in a way that was modular, custom, and cheap to print. Since then, I’ve printed several versions for friends and my own home studio.If you find this helpful, share a make, remix it, or show me how you customized it. Let’s keep building better tools for creativity. :D

As the 4All ecosystem continues to grow, I’m excited to introduce a new addition: the Rack4All — Storage Unit. While most of my recent work has focused on 3D printing accessories, this new module is designed to be much more versatile. Although the examples I’ll share here are related to 3D printing, the unit itself is not limited to that world — it’s a genuinely modular storage solution for any workspace.The Rack4All — Spools and Tags + Build-Plates + Storage SystemsTwo Configurations, Endless PossibilitiesAt launch, the storage unit comes in two configurations: a single and a double unit. Both can be arranged vertically or horizontally, just like the filament racks, and are fully compatible with the rest of the Rack4All modules. As with every module in the system, you can use the storage unit on its own or combine it with others to create a setup that fits your needs.Inside, you’ll find removable shelves that function much like drawers. Each drawer features a front tab that serves a dual purpose: it acts as a handle and provides a dedicated space for labels. This means you can identify what’s inside without having to pull the drawer out — something I’ve found useful when searching for the right part or accessory. The drawers are print-in-place, making assembly straightforward.The signature tilt present in all Rack4All modules ensures that stored items naturally settle in an organized way, making the most of the available space.Designed for Real-World NeedsThe initial motivation for this storage unit came from my own experience with the Bambu Lab H2D Combo laser, that has a LOT of items. I needed a way to store spare parts and accessories that were still in their original packaging — Over time, I’ve learned that it’s often best to keep certain items in their protective boxes until they’re actually needed. That’s why this module is fully enclosed — a conscious decision that might not appeal to fans of barebone, open designs, but one that makes sense for protecting valuable components.The Rack4All — Storage can be stacked vertically and horizontally, giving you great flexibility and the shelfs / Drawers optimizes your spaceOf course, I know that not everything stays in its original box forever. For items that are already in use and no longer have their packaging. This way, you’ll be able to mix and match shelf types within a single unit — storing both new (boxed) and used (unboxed) items side by side.To address this, I’ve developed a range of shelf and drawer combinations. For those who use the Gridfinity system — a popular choice in the community — there are now fully Gridfinity-compatible shelves, as well as hybrid options that combine Gridfinity slots with space for closed cardboard boxes. This means you can mix and match, storing boxed components alongside open, modular storage for smaller parts.Shelfs for cardboard boxes and with various degrees of Gridfinity sockets.It’s worth noting that while Gridfinity is very versatile, its standard grid doesn’t always make the most efficient use of the available space in the Rack4All modules. That’s why I’m planning to introduce a new grid system in the future, with different dimensions, to maximize every millimeter of storage.
