Pure genius in fastening technology. This hexagonal piece of metal, when paired with an M3 screw or bolt will hold your project together guaranteed. Granted they are quite small and fiddly, they’re your best alternative to glue anywhere. Grab one, grab a few. Theyre indispensible. At least if you lose one, you can still juggle 2 :)
