AR15 lower support plate for engraving
thingiverse
Made this to be able to engrave pictures/letters on an AR15 lower with my cheap 3018 CNC. Lower goes on top and this make it leveled. For one side only (left). The support plate is made by looking at a 80pct jig plate. I am including Freecad source. Sorry, no photos. But it works fine.
