This is a very simple wall mount for the BoboVR magnetic battery. There are 2 spots where you can optionally superglue (2) 8x3mm magnets so that the battery sits perfectly in place. The PLA will flex a little bit with the battery inside but it should be just fine.
To mount I just used some double sided 3M tape. Just give it time to bond before putting the battery in. You could also very easily add a hole if you want to screw it into the wall or something.
