Ender 3 Electronic Rear Mount
thingiverse
Yet another remix of this just didn't quite hit the mark for my specific needs. So, I took all the original components and gave them a complete overhaul, injecting a dash of inspiration from other remixes along the way. I added ventilation to the stepper drivers by bringing fresh air in on top and blowing stale air out over the Pi via a 6015 fan - both equipped with protective covers to keep dust and debris at bay. If things get too hot, I might even add a fan on the right side of my printer. My printer is situated relatively close to a desk, so I'm not too concerned about airflow coming in or out from the bottom. I also removed the relay mounts and swapped them out for a QuinLED Quad mount, which will allow me to utilize one of these clever LED drivers: https://quinled.info/2018/09/07/quinled-quad/.
