Guitar Pick Multi-Pick 12-String Effect

This MultiPick guitar pick is intended to (somewhat) emulate the sound of a 12-string guitar while playing a regular 6-string guitar. The multiple picks strike the strings in rapid succession providing a unique sound.

This design is based on an old expired patent (expired in 1999). Back in the 1990s, I bought a pick known as a "Strum Rose" pick but I can no longer find anywhere to buy one, not even used. So I decided to try my hand at recreating this for 3D printing.

Hopefully, the guitar players out there enjoy this design and I can't wait to see what improvements/variations can be made to it!
