Summary

I have done many small modifications to the original GoPro mount, they might not all be listed here:

• Added matter at the front to stiffen it
• Modified the shape in front of the TBS ND filter as I had TPU in the view before (other people didn't have this issue). I since figured out that having a lens protection film also helps reducing the corners in view.
• Allowed the (half) opening of the USB trap door (enought to charge it, no more need to get the camera out)
• Added holes to pass the screwdriver more easily
• Elarged the middle washer hole for easier mounting
• Adjusted openings location
• Added my logo (the most important thing tbh)

If some of these changes make sense to you, feel free to give it a try and give me a feedback :)

Update 1.1: Removed matter on the left side as well in front of the ND for those who were seeing the mount on the 4 corners of the video. I have not testprinted this version yet.
