I made my one printer box with some recycled materials.

Printed in 0.2mm layer height, 20% filling with PLA+, without support except for the hinges

The side plank have 10 mm of thickness and top/bottom plank have 20 mm of thickness.
For the screws I use ø4x30 for all the fixations except for the hinges on the door I use M5x16.
The magnets are 6mm by 1.6mm.

V2 : Rework the hinge holder to make it stronger
