Inspired by the tool box @Ken, I designed a larger one to store (almost) everything I need to handle my printer.

There are two optional parts to print:

First is a compartement for the “Easy to empty 45° Filament Cutter” @fuchsr which I find very practical!

Second is a simple support you can put under the tool box (see picture) to get a stable stand but keeping some space between tool box and PSU. Up to you if you want to use it or not.

Cheers
