Ender 3 Upgraded Control Case

thingiverse

Didn't look the factory control box so designed a new one. Adds a bunch more slots for airflow and moves the fan (or fans, should you want) from the lid to the side, blowing right over the stepper drivers. The lid just slides in and out, meaning you no longer have to wrestle with those cap heads under the bed. The front panel is slightly thicker so it's a bit more awkward to remove the SD card, but definitely still manageable. This requires that your printer has at least 3mm rubber feet, and AFAIK won't work on the Ender Pro. **Hardware Required: ** - 2x M3x12 (minimal thread) or preferably M3x16 screws per fan - 3x M5x8 bolts/washers/channel nuts Ignore the shitty prints on mine, dealing with a busted push-lock fitting on my extruder. **Instructions: ** -Print the control box and the lid, use whatever layer heights you want. Ideally use supports providing you've got them dialed in (so you can easily remove them from the lid slots). -Cut threads into the 4 mounting points for the control board and the fan bases - just pushing a M3 bolt into it and turning should do the trick. -Install one or two 4010 fans. -Pull the LCD ribbon cable off the hot glue, and remove the plug from the board. -Undo the 4 bolts holding the case onto the board. -Remove the pressed steel case (one bolt on the bottom, 2 on the front extrusion and slide it off from the printer, lifting the board up gently as you go. -Move the ribbon cable from running along the righthand side of the board to underneath the main loom and around the left. -Install internal M5 bolts/washers, thread the side channel nuts on and put the rear channel nut directly in the extrusion. -Slide new control box in, using the installed channel nuts as a guide. Be gentle moving the board around. -Slide channel nut to position behind rear mounting tab and tighten, install front M5 cap head screws onto the extrusion and tighten, finally tighten side cap head screws -Mount control board -Plug in LCD screen ribbon and fan connector.
