i used it for about a week and the collar broke on both sides so ive went back in an thickened those up and also added a 3rd size for the ball ends at 15.6mm so they fit a little tighter but that along with a few changes to the collar it tightens down alot better than before. so use the highest version of each part an u'll get the best results.

my camera is 33.40mm x 34.30mm x 33.65 an thats what i made all these for walls 2mm thick so u might be able to figure out how much to scale it to fit ur needs. i made a few different versions of a ball an socket mount for a wifi camera i have that i use with my printers an its been pretty handy so far. hope its helpful to someone else. if it doesnt fit ur camera let me know an i'll try to make one that will.
