LowRider 3 CNC SKR+Raspberry Pi Control Box

prusaprinters

This is a re-remix of Jeffeb3's remix of the LowRider3 CNC's control box. It enables mounting the SKR 1.3/1.4 controller, a Raspberry Pi 2B/3B/3B+, and LM2596 buck converter. Optionally, I also glued in 2 x Wago mounts to distribute power within the case. All screw holes are designed for M3 BHC.Changes:Lengthened case by 20mm to accommodate additional hardwareShifted SKR board back to make room for cable routing on all sides of the PCBAdded a 30x10mm fan to keep things inside the case cool(er)Rotated Raspberry Pi to externally expose ports and re-oriented to be parallel with the bottom of the case.Added mounting points for an LM2596 buck converter to power the Pi.Relocated V1 logo cutout to the right of the Pi to accommodate power ingress.Note: The taller blue heatsinks that came with my stepper drivers were a little too tall for the lid to close without touching. I opted to use some lower-profile heatsinks to resolve the clearance issue.
