I have been looking for a electronics box that has the lid on the underside of the printer but I have not found one so I made one myself. 

I have include the cad files so you can make it your own if you want. 

Whats in the box?

• 1 Raspberry Pi
• 1 SKR Mini E3
• 2 Buck converters (might have a slight variance in hole pos)
• 1 Noctua NF-A4x20 Fan 
• 7 M3 inserts for the lid.
• 2 WAGO 221-413 for power input

I have seen that not all Enders are the same, but it should fit okey on both the Ender and the Ender PRO.

The buck converters are for 5V to the Raspberry and 12V to the Noctua fan.

For anyone that only have a Ender 3 I'm sorry to say you need a printer with at least 300x300 bed to print this.
