Made entirely from scraps, aside from steel rod. Jaws are printed in PETG, feet are resin, though you could absolutely use FDM as well.

This is less of a how-to, as the random scraps I have laying about are certainly not gonna be the same for everyone. Just see what works for you.

FreeCAD files are included if it helps anyone. Also note the original website has SCAD downloads for their designs, which could also be useful for anyone attempting the same thing.

CC0. Have fun.
