Corner bracket for angle bars

thingiverse

I designed a holder, a roll and a cleaner with a screw connection a bracket to merge angle bars in a corner. In my case it is for the enclosure of my 3D-Printer. I used 20x20 mm plastic angle bars in black. The brackets are fixed with countersunk screws. The screw holes are prepared. You can also find a connector for two angle bars with a cable entry.
