Ender 3 External Control Box

thingiverse

Designing an enclosure for my Ender 3, I wanted to relocate the electronics box completely outside of the enclosure to make it more accessible and reduce the heat the electronics were exposed to. TeachingTech did a fantastic job with their design, so no need to recreate the wheel. Remix kept most of the mounting holes (excluding the buck connector and relay for the Raspberry Pi side since I don't need these holes). The other side is for the standard Ender 3 board, with mounting holes for the smoothers. I made a few dimensional changes to increase the box height to 50mm since it's not constrained by the Ender 3 frame, and closed off part of the back. I also modified the tops so they don't require the frame to stay in place. Mounting brackets were added on the sides of each box to screw into the enclosure. It is recommended to raise the enclosure above the surface to provide enough clearance for the fan to push out hot air. Original files can be found here: https://www.thingiverse.com/thing:3688967
