This is a remex of 2 items:https://www.thingiverse.com/thing:3688967https://www.thingiverse.com/thing:3380196
But remixed a lot.
This will fit an Ender 3 with an MKS GEN L version 1.0 with 3 buck converters, 1 Raspberry Pi B+ and a relay.
I use this:
1x buck converter to power Raspberry Pi (for OctoPrint)
1x buck converter to power LED's on my Ender 3
1x buck converter to power 3x 12V fans, 1 noctua for the hotend and 2 for the case itself.
Relay: to power on/off printer via OctoPrint
This fits very well on my Ender 3
No supports,
large layer height for faster printing,
PETG for no warping from the sun,
first printed with PLA but the sun made it deform. My printer is near a window. No warping noticed by the sun with PETG,
Good airflow, I think, at least never near overheating anything

2x case fans:
just any 60x60x10 mm fans you want. I choose 2x 12V fans so that I could use the same buck converter as my hotend fan is on.
You can edit this and make room for one more buck converter if you want that instead of the relay. That was my first design but because I didn't need it, I put a relay instead.
The USB cable that comes with the Raspberry Pi fits inside and the connector lies in-between two of the buck converters but you need to route the cable inside to fit well. I recently ditched this cable though and am using jumper cables straight from the Raspberry to the MKS using this guys method doing so:https://www.tardigradeoutdoors.com/blog/how-to-print-without-a-usb-cable-on-an-ender-3-and-octoprint
