the whistle - 1g loud dual note keychain

simple, but loud two tone keychain.
due to about 4kHz + 4,75kHz combination extremly noticable and loud. 

no supports needed. prints ~3 minutes, and uses ~1g of filament.

(i achieved ideally 1g with 10% infill and ASA) 


Print as many as you can and share them with the kids of people you don’t like 😉
Then come back and drop a boost as a thank you!
