You can print your own Peak Design wall mount. Needs 8 6x3mm magnets.
Both visible and hidden magnets. I kept the nub to provide a better hold, but you could cut off the extra part if you don't need it to be that secure.
Based on the step file that @JerrodH provided. Thanks for sharing Jerrod!
The author remixed this model.
Removed the compliant part of the design to create a simple wallmount.
