I frequently use a few specific aerosol cans at my workbench. I wanted to keep them off the worksurface (to make for easy cleaning and free up space). I made these little holders that use 10x3mm magnets to hold them in place (note, the ledge of the workbench carries the weight, the magnets just keep them from falling off).
Any material should do, nothing to support.
Nothing complex, just slice and dice, the print should come out nice...
