Having broken the original one, I just replicate it building a twin. It fit correct with Awning winding rod with diameter of 14.2 mm. UPDATE: after few time the first release went broken due normal operations; new version 2 is now in place and working: it has increased thickness (plus 0.5 mm) and closer lips to fix more tight the rod in position.Not too much to say: just print it and fix in position using two proper wall plug, considering the rod natural position (may be not horizontal). I do suggest to fix on the rod coupling area and then write on wall the right hole for wall plug position using a pencil.
