5th STEP File

This is the STEP for the "5th Peg" concept. I've simplified the model for ease of edit. Will require radius on inner (5mm thick) portion to avoid crank arm bolt. Chamfer 10mm thick side to tamper to your crank arm.

Also, you'll need to create the bushings that fit your particular spindle and the OD of the guard. I usually use .1mm to .15mm gap. Also, make bushings thicker than guard so you tighten onto the bushings and not the guard, duh.
