3/24/17 Released CAD File: http://a360.co/2mYSXa9
3/21/17 I just added the 10 card version as well
Edit 3/20/17 The main body of the wallet is now printed partially out of TPU while the rest is printed in PLA. While printing, you need to start with PLA pause the print at the 15 mm mark and swap to TPU
This model should still work only using PLA, but it has been redesigned for part PLA, part TPU
This the new version of my original design, linked here: http://www.thingiverse.com/thing:1648262 (Check it out to see how it was made and how to use it)
The most important difference is that it no longer prints pre assembled. Everyone had issues with it printing, and the tolerances could not be lowered otherwise the model would no longer work correctly, so it had to be printed as parts and assembled so that everyone could use the wallet.
Also, it now adds a money clip on the front of the wallet
