Quick model I made to mount this Wio Tracker L1 case in my attic. This is for static use only, not meant for mobile use.

It snaps in so it can be taken out and replaced easy to charge. If you want to mount it in a vehicle a generic clamp style mount would be better as this does not have the strongest hold. It can be shaken around lightly without falling out but thats about it. This is only the 2nd model I've designed so it's about as good as I could do.
