You can design and print the object with rounded corners where needed, or with a different fastening system that doesn’t scratch the camera.
If printed with PLA, ABS, or some other ridged plastic, you may be able to round the the corners post-printing with sand paper.
You may also be able to print the object with soft, pliable material like thermoplastic copolyester (TPC), but I don’t have experience with it since my printer doesn’t handle it.
Check this website for info on the plastics that are available:

I use GoPro knockoffs and designed and 3D printed frames out of PLA that the cameras slide into from the front. They are locked into place with two small ramps at the bottom and the springy clip on top. No round corners on the print, but no scratches on the cameras either. Removing the camera just requires lifting the spring clip and rocking the bottom of the camera over the two ramps on the bottom.
My camera holder is designed to slip onto a 3-axis gimbal.
I have versions where the camera is triggered with a servo and versions where the camera is triggered electronically by an autopilot (see photos).
I use SketchUp 2017 (the last free version) to draft my 3D stuff.
Before I bought a $200 Cetus printer (
Cetus3D - Minimalist Precision 3D Printer that simply works) on Kickstarter, I used local people found on 3DHubs.com to print my stuff. There were a half dozen people who could print in different materials within a few miles of my home. I don’t know what 3D Hubs is like now. See this site for a review of similar services:
