90° Corner Bracket for 15x15 Aluminum Extrusion (REV 15mm / Misumi Series 3)
A printed 90° corner bracket for 15x15 aluminum extrusion.
Three M3 holes per leg on 8mm spacing line up with the slot on REV 15mm Extrusion and Misumi HFS3 Series 3 profile. Triangular side walls brace the corner and leave a pocket for the screw heads. Print a stack in your team colors and keep them in the pit box.
Print flat for the best strength.

SolidWorks may prompt you to run "Import Diagnostics" to check for and fix any potential issues with the imported geometry. It is recommended to do so.
3D Printing Tips
If the design includes 3D printed parts, I highly recommend you print the part out of PCTG. It has some of the highest impact resistance and non-catastrophic breaking for robot parts.
For Mechanical/structural parts, I recommend:
- 0.6mm Nozzles over 0.4mm. Wider nozzles produce stronger prints in shorter periods of time over thinner nozzles.
- Minimum 4 walls.
- 30-40% gyroid infill
