Cap for GoPro Surf mount

This is a cap for GoPro surfboard mount.
I noticed like many that this GoPro support glued to the adhesive on our surfboard can be dangerous, especially when you don't put the GoPro camera. You can cut your foot, injure your head in the event of an impact... A solution had to be found to secure this support. After some searching, I couldn't find anything. So I decided to draw it.
You have to print this TPU cap so that the part is flexible but not too much. I did some tests, it holds up well on the board...but I didn't go so far as to take it into my head... ;)

I've design this thing with Fusion 360.

I've print it with Anet A8 in TPU.

Cura 3.2.0 : 210° ; 40° ; infill 20% ; 30mm/s
