My attempt at the rig mount for my NRG QR. The aluminum ones look very good but this does the same job so far :) 

My wheel weighs in at ~2.1kg(4.6lbs) and right now this is holding it up. Will need more stress testing at this weight so have created 2 versions (hollow and solid). Testing the hollow first.

Printed on P1S without supports but using standard Voron parts settings. Mounted using M6x16mm
