i3 MK3 tool bin

This thingy densely collects all tools that come with the Prusa i3 MK3, including printer cable, as well as a bottle of isopropyl, a bottle of acetone, a bottle of tool oil, and three additional slots for scraper, knife, and calipers. Note that screwdriver hole is slightly small and needs to be drilled or expanded with a hot screwdriver.
