Meet the Tiny Marble Run – a compact and mesmerizing 3D-printed gadget that's perfect for anyone who loves creative designs and simple mechanics. Unlike traditional marble runs that span multiple paths, this design keeps the action on a single wall, making it both space-efficient and visually engaging.
The standout feature? A large slanted-gear wheel! This gear transports the marbles from the bottom to the top of the track. The marbles slide into angled holes at the base and pop out at the top, ready to roll again. The motion is powered by a smaller gear with a hand crank, making it fun to interact with while showing off the mechanics in action.
The axles and crank handle are designed for easy assembly, using a press-and-twist locking system that’s optimized for 3D printing. The project has been tested with 12mm marbles, which fit perfectly into the track and gear system.
To make the process even smoother, I've included a test print file to check the fit and functionality of the press-and-twist system before printing the entire model, so you can avoid wasting filament.

I thought the assembly was quite simple, but I see that a guide would definitely help! 😊 So, I created a short animation showing how to put all the parts together correctly. I hope this makes the assembly easier!
If you have any questions, feel free to ask in the comments. I’m happy to help!
PS: Sorry for the animation quality, I’m still learning! 😊

I put a lot of personal time into each project I share here 🕒❤️. I do it knowing there's no real profit—apart from sharpening my skills 🛠️ and the joy of contributing something useful or fun to others 😊.
The points I earn on this platform help cover only a small part of the filament I use to create these models 🎯.
If you ever run into printing issues, please take a moment to check if the cause might be on your end 🔍🖨️.
Even with all the advancements in 3D printing, proper calibration, bed adhesion, filament choice, and profile settings still play a big role in the final result ⚙️🎛️.
Negative ratings affect a project’s visibility 📉 and reduce the number of downloads, even if the issue wasn't with the model itself.
If something's not working, please don’t hesitate to message me 💬—I'll do my best to help or clarify things 🙌.
This is just a small part of my life, but it’s a big part of my passion 💡. I’m constantly learning and improving 📚, and your thoughtful feedback makes a huge difference 💬🌱.
