Loud Emergency Whistle Keychain
Description
This is a compact yet very loud emergency whistle designed to go onto a keyring or in a backpack. It has a small hole at the back to attach to a key ring. Printed in PLA with 40% infil, using a raft for adhesion and support for the curved mouthpiece. It is important to only use support attached to the bed, as we do not want support inside the whistle itself.
