Perfect Change coin Holder

thingiverse

This coin holder guarantees you'll always have perfect change at hand. It securely stores $0.99 plus a $1 coin as its retaining lid. I plan to start carrying it in my everyday carry bag, but haven't field-tested it yet. The coins seem to stay in place pretty well, but I won't know for sure until I put it through more testing. If anyone creates one, let me know their experiences. I printed it at a .2mm layer height with 65% infill. Update March 13, 2017: I uploaded a "V2" version. The original was thinner and prone to fatigue. This updated design is a little thicker and also makes the slot smaller to hold the Liberty Dollar tighter. Note that this is still a work in progress, and I'm open to community suggestions!
