I recently changed to Klipper firmware to be able to easily add a second Ramps-Arduino for 12 volt temperature controlled fans. The space next to the printer was a mess so I decided to combine it all into a single enclosure. The current setup is ramps 1.6-mega on the left side and a ramps 1.4-mega on the right side. Raspberry pi is above the ramps 1.4. I also relocated the LCD adapter board to allow cooling for the raspberry pi. If there is interest I can add a case front for 2 ramps 1.6 or 2 ramps 1.4. If you have any questions, please ask. If you print it please post it.
