While I love the Tyvek Wallet solution having a more solid case is sometimes the needed solution. In a previous post I went through some case solutions from things you can find floating around the house. This is a post about a 3d printed wallet I found on Thingiverse called the Eulidit that I slightly modified for my needs. I am still tweaking the depth of the thing, the current model might be great for backpacks and handbags but is just about as thick as I can fit in my jacket pocket. It does hold my cards and some cash, which is in keeping with the PiFold as wallet idea, and has the right openings to make recharging fairly easy.

I am going to take it out on a test drive during today's living. You can try out the current model here.. http://www.thingiverse.com/thing:1389474
