Pi Keychain or Pendant

thingiverse

The Pi Keychain by LINUX was a hit, but I wanted to take it up a notch - literally - and create a version with a larger round hole that could fit a standard keyring perfectly. So, I downloaded the original .stl file from LINUX's design and got to work editing it in Tinkercad. The finished product measures 22 mm x 27 mm, and what's more, I didn't need any raft or supports to get it just right. We also gave some of these keychains a new lease on life as earrings by adding standard earring fittings - the photo shows one next to a quarter for scale.
