2020 Corner Gusset

thingiverse

This is a straightforward corner reinforcement bracket that can be paired with any 2020 aluminum extrusion to guarantee that the extrusions stay perfectly perpendicular to one another. For optimal results, two should be printed for each corner and the extrusions need to be placed between these brackets. There's a deliberate gap left inside the bracket to accommodate a standard aluminum gusset, providing extra reinforcement.
