If your 3D printer is too loud for your liking, this video guide is for you. We cover how to make it quieter while it is printing, as well as making it completely silent when idle. In my case, this means I can have most of my printers sitting in wait for a print job to be sent to them wirelessly.

The guide covers using quiet Noctua fans using a buck converter, even with PWM control, as well as relays to switch off unneeded fans and power supplies. With firmware instructions for Marlin, RRF and Klipper, your particular machine should be covered.
