Camera mount for Tiny Trainer

This is a loose remix of the original camera mount (Foxeer nano https://www.thingiverse.com/thing:4315912) for Tiny Trainer. I modified it to:
- allow longer lipo to mount more forward for better CG
- shifts camera a bit forward and lower to prevent cam plug hitting frame on impact
- bigger rear hole for cam to go in/out easier
- easier print without need of support

I personally printed at 0.28mm layer height for speed, 3 top/bottom layers, 2 walls, 100% infill, no raft/brim/support. Print with cam hole facing bed.
