tpu coin holder

thingiverse

I no longer carry coins in my wallet, but the jingling noise irritates me and I detest rummaging through my pockets to find them when I need them, so I came up with this solution. This design is intended for printing on TPU, making it flexible rather than having a rigid object in your pocket, and the TPU won't bang against other items. There's enough space for two coins per slot, which is more than sufficient to allow you to give exact change when this design is full. This was designed specifically for US coins, but the model is fully parametric, making it easy to modify it for different coin sizes. The TPU's stretchiness allows you to push coins in, but prevents them from moving around and rattling. I printed this design on Sainsmart 95A material, which has a smooth surface perfect for pocket use. If you print with a different material, please share your experience by leaving a comment!
