Used the excellent desk mount from here:

Shredded it in tinkered and made it into a pillar or wall mount.
This is kind of rough, but it gets the job done. Attach a Quad Lock head of your choice to it. I am using the wireless charging head.
Printed with supports, as shown. .4mm nozzle, .2mm layer height. Four walls for extra strength.
