quad lock mount for modular mounting system

I'm new to 3d Design and I literally just took two designs and put them together...

You can find them here:

I printed it in two parts to screw them together because it's much easier to print and i wanted to make sure the quad lock part works before I print anything else.

**** IF YOU WANT TO TRY THE QUAD LOCK PART YOURSELF BEFORE YOU PRINT THE REST MAKE SURE TO ATTACH TWO SCREWS TO GET SOME LEVERAGE, OTHERWISE YOU'LL HAVE A REALLY BAD TIME TRYING TO GET THAT THING REMOVED FROM THE BACK OF YOUR PHONE****

Printing them together would be a really bad idea because the quad lock part has to be really precise but feel free to try it and be sure to post your make!
