TicTac Shooter - recessed M3 hex bolts

In order to have the bolts sit flush with the surface of the tictac gun, I added a negative volume for each.

To do this yourself, right-click the gun part, add negative volume, select Load, and pick the m3-hexnut.step file. Center it around each screw hole, and make sure it's just barely touching the built plate.

Enable support material “on build plate only” for cleaner result.

Use 16mm M3 screws for a perfect fit.
