GoPro Max 360 Backpack mount

This is a backpack pole mount for the GoPro Max 360. The Anti tilt GoPro mount to go with this is posted separately. It is designed to fit a standard 8mm x 8mm carbon tube that can be purchased from hobby shop or online. I use it for windsurfing using a 1 meter rod but of course can be used however you wish. The 3D printed part is bolted onto a cheap plastic cutting board purchased from the supermarket (I got pack of 5 for $8). The cutting board you cut to size for the backpack you want to use for a snug fit. If using a safety leash you tie this to your backpack. This particular mount has a 20 deg angle too the chopping board which if used for windsurfing seems about right to not hit sail or water. Initially I used 10 deg but the camera kept hitting sail as I launched. I printed in PETG with about 50% infill, no supports. So far it has survived many heavy duty windsurf sessions. The tube is a tight fit but I drilled a 3mm hole once the rod in place to fit a bolt
