I have various video / photo gear and one is the Soloshot 3 Robot Camera system.
I really do not want to mount my tracking Tag on the centre top of the shell ... so have been looking for ways to mount it.
I found an FPV mount that is fitted via the screws for legs ... same as my GSM Tracker. The size as downloaded from Thingiverse is slightly small and does not fit the P3P .... but I am scaling the item and have found that using 1.09x scale - it fits after a small modification to where screws pass through it... the arm ends are a bit wide ... so clipped them back a bit. I also made more clearance for the antenna wires.
