This is meant to be hung with double-sided tape but the Solidworks file are there if you want to make modifications to add screw holes or something like that. I created the parts in one file so one file has both the bin and hook. The stl contains both the hook and bin, so if you only want one of them then split them to objects in the slicer.
It has a 3mm thickness so it can stand on its own and it won't be crushed if you bump into it.
