I used to sell 3D-printed camera gear (GoPro parts among that) but found that I dont have time for it anymore. I decided to share my models instead.
Print with ABS, PETG, ASA, Nylon or any other strong material. Insert a M5x25mm screw (you need to push it in so that it locks with the built-in clamp)
Enjoy, and if you like it. Please share, send me a thank you on twitter and subscribe to the youtube channel maybe? https://www.youtube.com/c/amidse
