Ender 3 External Mainboard case 3D print model

External case to put on the side of the Ender 3, Ender 3 Pro, Ender 3 V2 - Ender 3 Pro - Ender 3

Designed to fit a 80x80x25mm fan (Arctic in my case)

For the fan, I've use a buck converter 24V to 12V and plugged the cable directly on the Power Supply.

You'll find two box design :

• The first one (BoxV1.stl) with simple hole to fix the cover to the box with self-threading screw.
• The second one (BoxV2.stl) where you'll need to fix M2 nut with glue to the box. Then fix the cover to the box with M2x4 screws.

To fix the Mainboard on the Box, you'll need :

• M3x12 screws and M3 nuts. (x4)

To fix the Case to the Ender 3, you'll need :

• M4x6 screws with T nuts (x4)

To fix the fan to the cover, you'll need :

• M4x30 screws and M4 nuts (x4)

Results are great : better airflow and a lot more quieter.
