TBS Sourceone v3 Hero 3/4 mount (No Jello!!!)

I tried out several other online available hero3/4 mount designs for my s1v3 7", but they all resulted in major jello. So I set out to design my own, focusing on advice from Oscar Liang that a harder mounting is better than floating. The devil is in the details when making a truly “hard mount” from tpu. In this example, finding that key detail that stopped jello completely required testing no less than 5 minor revisions of my design.

The important changes that made my latest revision (rev. e) work so well was widening the bottom couch area, and adding small “speed bumps” on the outter edges where the camera sits. I did this because I observed when any TPU plate is tightened to the frame, it will warp up and allow movement near the center of the plate (right where the gopro mostly depends on support). On my previous revisions, this made a small like 0.5mm gap that allowed the camera to rock and roll slightly when forced around by hand. The small bumps apply pressure at the just the right spot to counteract the warping and stop this movement. The new mount feels far more rigid. Several aggressive test flights later, this design has proven itself jello free and worthy of upload.

Print as oriented in the stl… supports are required. I used Amazon basics black TPU, an 0.4mm nozzle, 0.25mm layers, 2 walls, 40% bicubic infill, 5tops/bottoms, with no brim on bare borosilicate glass. Screw the mount to the frame with the stock screws, adding 3mm washers to keep the heads from damaging the tpu. The camera slides in/out with a lot of friction so it can't pop out on it's own.

Enjoy, and keep ‘em rippin’!
