Holder for 25A Mosfet. Uses M5 bolts to attach printed holder to 2020 extrusions and M3 heat set inserts to attach the mosfet board to the printed holder. 

I printed mine out of ASA at 101% scale for plastic shrinkage. I used M3 heat sets that were 10mm long and M3x10mm socket head cap screws and 4 M3 washers.
