I did not like how the original variable angle GoPro mount because it did not hold the camera very tight. I never had an issue with it falling out, even after a crash the camera did not move. But still, I rather have a mount that is a bit tighter. So I combined the following files to make what I have now.
and the variable angle base:
Just like the original variable angle mount you will still need to use a m3 x 20mm standoff inside the base.
I also remixed the bottom mount so it is a little thicker where it mounts to the frame. The bottom is now 2mm thicker.
Update: I did some test with infill and notice a huge weight difference:
Infill @ 75% - total weight 15.47g
Infill @ 25% - total weight 10.80g
Shendrones Squirt Variable Angle Hero Mount - 9.37g
For something like the Squirt, I would like to get it as light as possible. With the infill at 75% it had the tightest fit, and with 25% infill it was not bad either. The orginal "Shendrones Squirt Variable Angle Hero Mount" had the least amount of grip on the camera and only weighed 9.37g. So with a tab more weight I am willing to sacrifice 1.5g to make sure my GoPro will NOT fall out.
Warning!!! This model is a cut and past job, so some slicer apps might like it. I know for sure Cura was able to handle it. Sorry, I do not know how to properly building 3d models.
I printed the gopro case on its side, with the lens side up. The base plate can be printed without supports.
