2020 Brackets Collection

Various 2020 connectors I've designed and been using.

Print the plates with the counter-bored side on the plate (2020 inserts up) with supports.

Usage should be self explanatory with the exception of the Joiner Plate, that's used to join two extrusions, braced with another smaller extrusion centered on the joint; 3d printed extrusion for the brace seems to be sufficient.
