Don't throw you empty Toilet paper rolls away.
Here is a simple solution to reuse them in a proper way.
The parts are for Ø42 rolls, if it not fits yours simple scale X/Y direction.
I added custom brim to the hinged part for good adhesion.
On the second buildplate you find a top part without a lid. (Good as pencil holder)
Enjoy the files! Happy recycling😃👍
