Need to attach your Megatronics v3 rev. f board to your P3Steel frame? This mounting plate does just that. Mount it to either side panel of the frame, and since the P3Steel frame mounting points are in the center, you can mount the Megatronics board in either vertical orientation.When I assembled this, I used M3 nylon nuts--the kind from PCB standoff kits--as a simplified form of locknuts.Please feel free to post any questions or suggestions!
