Acrylic paint tube stand for 18 tubes with a 25mm cap diameter

I could only find stands for 25 or 15 color tubes, so I made one 3x6 stand. Each triple compartment is risen 5mm to the next. You have to organize the tubes a little diagonally, because I wanted a stand that needs little space. Have fun.

Printed test model has a black bottom because I used some old filament leftovers.
