Rubber Ducky Hitch

I scaled up the ducky, removed the hole, and inserted the hitch portion from the claymore hitch. I have printed this myself with the settings listed, though you can probably change them significantly as I wanted mine a bit more rugged and to ensure that there was minimal drooping on the bridging sections. Please check dimensions prior to printing, as the hitch section was slightly too large on the file I printed (I have modified the file so that it should be ~51.5mm/2" OD).
