GoPro 11 Black Mini vertical skeleton frame mount. Simply slide in the GoPro and install it on any GoPro-compatible base. All buttons are accessible. Fits perfectly and securely. You can use it with larger ND filters like TELESIN as it's demonstrated in the photos.Includes the 3D Printed skeleton frame only.

I wanted an easy-to-use and low-profile vertical mount for my Hero 11 Mini, so I sketched this up in Fusion 360.

It needs to flex open a little to insert the GoPro - I printed in PLA+ which seems to work fine so I don't think other materials should be an issue, but if your filament is fairly brittle, it might be better to use something like PETG that flexes more.
