Hook to hang stuff from on the garage shelves from Bunnings or where ever These have lasted me over a year. Printed versions in PLA or PETG on X1C & Ender3 both are fine for hanging tools. Working on shelves with holes of about 12mm upper hole, 7mm lower hole and 1mm metal thickness.
This is brilliant! I have a ton of these shelves in my garage and kept meaning to figure out a way to hang more stuff on them. Thanks for sharing :)
