3d printed gopro swivel mount testing
Trying out the gopro swivel mount I found here: https://www.thingiverse.com/thing:292...
The tail fin was made with a threaded rod and some scrap aluminum since those pieces aren't included in the print files.
I'm guessing instability is due to the size and/or shape of the fin, improper tension on the main bolt and possibly placement of the mount.
