Sorry for the long delay… I finally managed to find the time to fine-tune the camera mounts for my super lightweight pepperF1SH quadcopter design. You can find the source files in the FreeCAD format and STL files at my pepperF1SH github repository.
In addition to that I also uploaded the STL files to thingiverse, you can grab them from my fishpepper account here: https://www.thingiverse.com/thing:2350617
The parts are best when printed in polyamide using a laser sintering service such as shapeways. But I also printed some of those in PLA using an extrusion printer. Enjoy!
