Tool holder for Prusa Mini

This is based on the Tool holder by Gilly Barr and the Loose Filament holder by LJ. I wanted a bit more space. This one holds tools in a 20 x 30 mm box and has dedicated holder for a 2.5 mm Allen key and a scraper tool. The housing to mount it on the aluminum extrusion (from the filament holder) is a bit more robust than the version from the original tool holder. Print upside-down, no supports.
