Corner for 2020 Profile - M4 & M5

This is my simple design of a Corner Bracket for 2020 Aluminium Profiles. Since i'm currently rebuilding a Hybercube 3D Printer and wanted to order as few parts as possible from China due to the long shipping time i decided to simply print the Corners for the Cube. I increased the Wall thickness of the plastic part to 3.6mm (physical Wall thickness not printed wall thickness/perimeters) and make them 20mm wide, i found the original corners are actually 17mm wide, as well as some Designs here on
