Nexus 6 case with credit card slot

I searched for a wallet case for Nexus6 for a while and could not find anything with card slot in the back.

I took wittyman37's design, added the honeycomb grid to reduce amount of filament and added the piece for 3 credit cards (or 2 cards & driver license).

I glued the card holder to the cases back with super glue.

I am planning to put it in an acetone vapor to make the surface smoother.
