Airhorn squeeze ball
Description
This is a squeeze ball attachment to jburin1982's Working Air-horn. It allows the horn to be operated without blowing into it by mouth. The ball has to be printed from TPU, NinjaFlex, or other flexible material. It holds and seals against the air intake part of the horn without any glue. The design features 3 separate files, ball with the hole on the side, ball with the hole on the top, ball with no hole. However, the hole is essentially required, since the air can't go through the horn backwards. So if you decide to print the no hole version, you will have to drill the hole afterwards. You need to cover the hole with your palm or finger when you compress.
