Ender 3 Quiet Control Box

thingiverse

A replacement for the mainboard housing that revolutionizes the Ender 3's electronics setup, consolidating everything into a single box efficiently cooled by a powerful 120mm fan. This upgrade replaces the noisy stock fans with a much quieter setup, utilizing a standard mainboard, a Raspberry Pi 2 (or easily remixed for a RPi3), and a buck converter to drive the 120mm fan. The design boasts two distinct layers: one housing the PSU, buck converter, and power socket, and another dedicated to the mainboard and Raspberry Pi. The 120mm fan is secured with screw-less adapters, making it effortless to remove for access to the mainboard and RPi. To minimize waste, I've made a conscious effort to reuse as much of the original hardware and screws as possible. All you need to add are five standard PC case screws to complete the assembly. The build process is straightforward: start with the bottom layer, followed by the middle layer, then attach the fan adapters, place the fan on top, and finally remove the screen from its stock mount and screw it into the top cover for a seamless finish.
