The side door handles supplied with my Qidi (May 2017) had a larger base diameter of 22.3mm however so I quickly modelled ITinSeattle's design. Work a charm, and figured I would upload for use by others with these newer type handles.
Ordered 5 x 1mm magnets off of ebay for very low cost. A good enhancement to the printer as the doors often went past the closed position, which this eliminates....as well as satisfying my OCD!
Raft optional - dependant on your confidence with your bed adhesion. Bottom is hidden by the door anyway so I didn't bother.
