A good way to organize your desk.
Organize your tools and pencils depending of their size.

You will need 6 empty prusament spools for this project.
It is very easy to assemble it.
Just put the base first and then 3 cardboard rollers.
Depending the shape you want, you can next put the joint or the top cover and so on.

To be nicer, be careful the stamps of the cardboard rollers to continue!

The only thing you need is your empty prusament spools and your 3d printer

I used Prusa PLA silver filament, no supports.
