I wanted to do a filament swap to create the side decorative pieces, so I sliced it up and made the "GripReceiverSidePlate_Engraved" pieces into a top and bottom. I didn't make a left and right, as I just used the 'nut' side for both, since there was enough clearance for the screw I was using.

Added a version of the DerringerReceiver, adding the engraving to the magnet version, and slicing out the sides so they can be printed separately and/or modified as desired.
