This remix of the Smart Wallet is from what I believe are improvements.

The lid and base are the only models remixed.

The lid has been thickened and a lip was added to the top piece which stops the cards from coming out.

This change to the card stopper is to keep the lid from flexing away from the base and allowing cards to unintentionally fall out.

The Base has been thickened and a space left for the now changed card stopper to lock in and be flush with the bottom of the base.

Overall this remix allows the card stopper to be more secure and the lid unable to flex away from the base. Unfortunately the lid now require support structures on the lip of the card stopper and support for the bottom of the base to print the card stopper lock space.

The thickening of the base and the lid are each 3mm and a total of 6mm of thickness was added to the entire wallet assembly.

This was remixed by Tinkercad. I was unable to have access to Fusion360, I am on vacation and my laptop does not handle Fusion360. The thickening of the models are just a result of methods via Tinkercad and are slightly offset. However this should not affect the overall print, it is just annoying. I will more than likely update this remix to fix this. Maybe the original designer will give me access to the original design files as to make a better remix.
