Batman vs. Superman Batarang Money Clip w/ Micro SD Card Slots

This design is the latest  Batarang money clip with (2) micro SD slots and (2) 10mm dia. x 1mm thick magnet disc holsters . Can hold about 25 bills, maybe more. I don't know. It comes in 4 pieces: 2 wings, 1 push/pull screw type (2 pieces, but it's not a screw though, I had trouble designing a special screw bolt.)

This is my first CAD design. Took me about 8 hours to figure out how to use a 3D software (basic tools for now). I'm really impress by the turnaround, sadly I do not have a 3D Printer to see this design come to life and to see if I'd properly measured everything. 

Please download, put your new Bataring money clip together and let me know your thoughts! :-)
