Mr Toothy v2.0

thingiverse

This model prints effortlessly without supports, snapping together seamlessly. Mine assembles with ease, and the lid stays securely in place even when turned upside down, but can be easily disassembled by hand when you need to open it. The fit will ultimately depend on the precision of your machine's printing accuracy/tolerances. It is designed to snugly accommodate a £2 coin, but it can actually hold up to three £2 coins inside if you want to add more. I'm glad I remixed and printed this when I did as my daughter pulled out her first wobbly tooth tonight!
