Gopro mount for Mark 4 5 Inch drone (GEPRC / Readytoski). Mount to frame with M3 bolts. Use M5x20 inner hex and M5 nut to mount the GoPro. Props are not in view!Zip file contains all the inamges, STL, STP and FreeCAD model. I've printed it using PLA and it serves the job super. TPU would be the better material.
