20ml Paint Tube Holder in different sizes

thingiverse

This Paint Tube Holder accommodates a maximum of 32 paint tubes at once, offering several versions tailored to different sizes and orientations, including single-sided designs. The paint I use measures 29.5mm in diameter at its end, fitting snugly into the holder. This design also works seamlessly with smaller 12ml tubes. It has been thoroughly tested with Talens 20ml tubes and Winsor and Newton's 14ml Gouache tubes. The walls of this holder are 2.4mm thick, making it sturdy and reliable when printed with a .4mm nozzle and three walls. In my case, printing with two walls proved perfectly acceptable, and even a single wall is likely sufficient. The largest version requires approximately 250-300g of filament for 10% infill. This holder has been engineered to be simple to print, eliminating the need for supports or extensive clean-up.
