Prusa MK3 - Smaller SideBoxes for some Tools - fits under bed in the back

This is an edited version of this Sidebox ( https://www.prusaprinters.org/prints/974-prusa-mk3-sideboxes-for-some-tools ). I needed a place to place some electronics, like a stepdown converter, on my MK3s. The original box was a bit long, 15cm. This version is 10cm long and fits under the bed.
