Aluminium "20 x 20 Bracets
thingiverse
These are a couple of brackets I've made for a laser engraver I'm making. The brackes hold the 20mm x 20mm Aluminium section together. They are a tight fit, so you have to slightly shamfer the ends of the aliminium to start it off and then hammer it into place. You will need a 5mm drill and some 5mm screews and nuts to hold it in place.
