Geeetech i3 Underbed ToolBox

My desktop is constantly short of space and gets cluttered by tools in a millisecond, so I'm struggling to keep it tidy.

This tools holder is designed to fit under the heated bed of my Geeetech i3 and should be able to host all those tools and items I keep around, like:

* Allen keys
* screwdrivers
* wrench
* digital caliper
* pliers
* screws, washers and nuts
* nozzles and throats
* nozzle cleaning drills
* etc...

All walls are `0.8mm` thick, to match with a `0.4mm` noz
