https://www.youtube.com/watch?v=PGjCF3DQE18 8/10 port air raid siren! The motor is a 51k60a-ba 115v induction motor from a New Hermes engraver. It is configured to spin clockwise. This can be printed on a stock ender 3, but it is critical that your printer is square before printing the parts otherwise it will rub. I highly recommend a dual z kit be fitted before printing.
