3 Bays Box for Hex Tiles
Originally built from TM Tiles, it can be used for whatever you want.
Originally printed with a 0.4 nozzle.
It requires some STL manipulation to assemble the parts before you can print, so you can change the size of it.
Or ... you can use the 2 STL files for the bottom and the cover, allready made for a 22 cm box.
