Remixed SG-O's mount to mount on the wall. There are some other versions of this wall mounted Vive controller holder/charger, however they are not as durable/sturdy as I'd like. These mount with two screws very solid on the wall. Remixed this in such a way that only the bottom surface on the build plate needs support. lordmundi's charger insert included here works wonderfully as well.
These magnetic charge cables work perfectly here: https://www.amazon.com/gp/product/B01MZ634EJ/
