Ender 3 pro Raspberry Pi4 B case with step down converter

It has a fan hole for 3010 fan and you can attach the step down converter to the top of the case (if you want to use the raspberry without the charging cable).

You will need 8 M3 3x5mm threaded inserts, 4 to connect the top to the bottom and 4 to connect the step down converter to the top. And you will need 8 M3 x 6-8mm screw and 4 M3 x 15mm screw with 4 M3 nut.

You will have to remove the X axis tensioner while you set it up.

If you have any question or I can help you with anything please leave a comment. Tell me if I missed something and I will correct it as soon as I can.

You have to use support (at least I used) for the usb and utp connector holes and the rails to connect to the frame, but you shouldnt use support for the camera cable hole becuase it's really hard to remove if you do.
