Smartphone adapter for tripod, quick release

You have a tripod.... you want to use your smartphone to film something....
That was my problem.....
So i designed this..... this is version 4... the other versions will not be published due to issues.

You will need 2 screws from the file. Or use M8 hardware.

For me it works fine, the only post-printing i did was use clean up the M8 thread on the screws and holes....
