Shopping Cart Coin Holder

thingiverse

UPDATE: I've got a newer version that's a bit easier to assemble and takes up less material. http://www.thingiverse.com/thing:1508063 Never be caught off guard without cash for a shopping cart again. This design attaches easily to any keychain or keyring and holds only one coin. The included files are designed for a Canadian $1 coin, but it's fully customizable so you can adjust it for quarters or other currencies. I found that printing with my Dremel printer using Dremel PLA and the free Print Studio at 100% fill resulted in a perfect print with no gaps, a snug fit, and just a bit stiff. After cleaning up the parts with a blade, I tightened them together in a vice and secured the back seam with crazy glue. UPDATE: I've posted an older version without some of the settings to make printing even easier. Simply set "ForPrinting=1" to space the model for printing. Print Settings: Printer: Dremel Rafts: No Supports: No Resolution: 200 Infill: 100%
