UPDATE: 12/20/14I rounded the edges on the top of the wallet so its more comfortable in pockets. I found this CNC wallet on kickstarter.http://www.kickstarter.com/projects/506932810/poquito-more-than-a-little-wood-walletIts a cool project but I thought it was totally 3d print-able.  So I gave it a go.  It is designed to work with those bracelets you get from conventions or awareness stuff.Like these:http://www.speedywristbands.com/order-now.htm#1I pre-ordered the "coin" (https://onlycoin.com/) and am planning on using this as my wallet for it.If you like the CNC wood wallet you should totally back it on kickstarter.http://www.kickstarter.com/projects/506932810/poquito-more-than-a-little-wood-walletI used the BRIM setting in CURA on my Ultimaker v1 to print this using PLA.
