20ml Paint Tube Holder in different sizes

thingiverse

This Paint Tube Holder holds a maximum of 32 paint tubes. There's different versions available for different sizes, as well as only 1 side. The paint I use is 29.5mm at it's end, which fits perfectly. This will also work for smaller 12ml tubes. It has been tested with Talens 20ml tubes and Winsor and Newton 14ml Gouache tubes. The walls are 2.4mm thick. If you print with 3 walls (with a .4mm nozzle) it will be solid. In my case printing with 2 walls was perfectly acceptable. Even just 1 walls is mostly likely fine. The largest one comes out to about 250-300g of filament with 10% infill. It's been made to be easy to print. No need for supports or any sort of clean up.
