Created this bracket to be strong and rigid when connecting two extrusions together. It was created in response to when an extrusion is placed perpendicular to another one. There was no supports in the cut out that would make the joining more rigid. This was created to solve that. You can see in the picture how each bracket fulfills it's purpose. This was originally designed for the AM8 Reinforced but can be used for more applications.
These were designed to be printed on there sides. The extruded slots have a chamfer on them on purpose to allow for this to happen. No supports are needed but good part cooling fan is recommended if printing in PLA.
Print with high infill and perimeters for max strength.
6/29/2019 - Changed the tab width from 4.8 to 5.4mm. This should press better in the slots.
