This is a case for an Einsy Rambo Board with room for a Raspberry Pi 3b/b+/4 and buck converter that fits the Bear Upgrade v-slot frame.

STOCK FRAME VERSION: [https://www.prusaprinters.org/prints/30296-einsy-rambo-raspberry-pi-case-for-stock-frame](https://www.prusaprinters.org/prints/30296-einsy-rambo-raspberry-pi-case-for-stock-frame)

Does not require extended PSU wiring!

The Einsy board is positioned at the same height as in the stock Prusa Einsy box, so the stock PSU wires will reach.

Supports connecting Pi via USB or GPIO.

Supports wiring for MMU2.

Update 02-21-2020:
All parts with "2-20-2020" in the file name now print WITHOUT SUPPORTS! Even the Lid!
Increased wall thickness of box sides to stiffen it up.
Added more space between the Einsy and RasPi boards to make it easier to connect the GPIO on the Pi.
Lots of other small changes and improvements.

Update 09-14-2019:
I finally got around to installing the Bear X-axis on my printer, and what do you know the board box was interfering with the X motor. I have fixed this by moving the entire box inboard 3mm.
I also added slots for square nuts at the cover fasteners.

Update 07-09-2019:
Added version for Raspberry Pi 4 (untested by me but should work)

Update 07-04-2019:
Increased clearance to x-axis motor.
Optimized features for FDM printing.

Update 06-24-2019:
Added optional cover with mount for 40x40x10 fan.
