Summary

Upgraded the top bracket of the xbox one wall mount (credit to Wupinstick) to hold the xbox controller, designed specially for this bracket.

Printed 4x walls, 6x top and botton, 10% gyroid infill and it's a bit overkill. 2-3 walls should have been enough I think.

The mount can be screwed to the wall directly. There are 3 positions as I wasn't sure which height will be the best for me.
