3D printing files discussion

A side project I’ve been tinkering with for a while addresses the interest in emergency key holders—specifically those where your cage key is kept inside and secured by a single-use plastic lock. It’s easy to see why people are interested, as I’ve reviewed various designs available on the market, including some homemade options. I wanted to add my own twist to this concept, and I hope you like what I came up with! CPUKW9x.jpg The Pocket Safe measures about the same as eight credit cards stacked together, making it a comfortable fit for pockets, purses, or wallets. It can accommodate keys up to 60mm long, 30mm wide, and 3mm thick. The rectangular interior is spacious enough to hold several keys if needed! Beyond just keys, you could also store the combination note inside. The locking mechanism accepts single-use plastic locks of a specific shape, which excludes some existing styles but offers a distinct look. Round-topped locks from CB-X and their clones fit well, as do longer variants. Gallery: The Cherry Keeper Pocket Safe is available in my Shapeways store for $29.95 in all colors offered I can also produce these in various colors and ship them within the US more affordably (Paypal only - $20 with first class shipping, plus extra for other options), though there is a slight reduction in quality. The appearance will match the photo above and the gallery images. Please reach out if this option appeals to you. I have included the STL file so you can print it yourself using a 3D printer - I used PETG with .2mm layer height for mine.
