This is an Electronics front enclosure for Ender 3 V2, it is designed to fit:

Bigtreetech SKR 2

Raspberry Pi Zero 2

1x Noctua Fan 92x10

Needs the feet extensions already installed.

For specific to the parts I had available and the limited length cables I had. It's very difficult to work on once it's in.

I'm making improvements over time but it's big & expensive to keep printing for small changes.

Print Settings

Notes:

I printed it in Hatchbox PETG for improved heat resistance but it's very flexible, which is noticeable when mounting and the whole thing flexes.

While eSUN PLA+ is much stiffer, I wasn't sure on how hot it was all going to get so plumed for PETG.

How I Designed This

I made a lot of variants to get to this point as the whole thing is very densely packed and there's no room for changes. I tried inverted (same as the stock mount) and various positions & orientations.

Specifically aimed to keep the cables as close to the back-left as possible as I run a Hemera direct drive and the provided cables barely reach this position.

rPI zero 2 mount is separate and fixed with 2.5mm screws through the front grid.

From front - grid of holes are partly air flow, partly where the rPI is mounted

right said - just a 92mm noctua. Optional shelf ledge

Left side, tightly packed. SKR, rPI Zero 2 and buck converter for fan
