Description

A simple modular wall-mounted marble track that uses reusable putty instead of screws, nails or tape.
Easy to reposition, safe for walls and fun to experiment with.

Updated V3

Version 3 includes improved track modules with refined geometry and more print-friendly designs.
Several parts have been reworked to require less support material, making them easier and quicker to print while keeping the system modular and easy to use.

The set includes multiple track shapes, connectors and a loop section.
Just press reusable adhesive putty into the back of each module and stick it to any smooth wall — build, adjust and rebuild in seconds.

I would really appreciate feedback, ideas and suggestions.
If there’s interest, I’ll keep updating the design with more modules, improved geometry and additional features.

Build, adjust and rebuild in seconds. Have fun experimenting!

Compatibility

Compatible with marbles from 10 to 18 mm.

Mounting

Any reusable adhesive putty should work.
You can probably use tape as well, but be aware that it may damage the paint on your wall when removed.

Printing

Print with supports where needed, with the wall side against the build plate.(except corner V3) 
V3 has been optimized to reduce the amount of support required compared to earlier versions.
