BigtreeTech SKR 1.3 enclosure for Makerfarm 10" Prusa i3v

thingiverse

This design was created to fit perfectly on my Makerfarm 10" Prusa i3v where the ramps board once resided. The design was crafted in Fusion 360, which I've included along with a couple of other versions of just a case without the extra mounting holes at the outside bottom of the case. This also features a spot to attach a 2-to-1 Z-motor splitter board. I purchased this splitter board from an eBay store, but it should be similar in size to others. You can simply remove it from the Fusion 360 model if you don't need it. The SKR model used as a reference in the design was off by about a millimeter on the first prints, so I adjusted it to fit better on the board I have. There are four mounting holes for the wooden frame, but I only used the top and inside bottom hole, as that's all that was necessary. I utilized a model of the board from an exported STEP file on GrabCAD as I recall. Initially, I just made a modification of the cooling tunnel referenced in Remix and created a simple mount for the board. However, I then took the other referenced remix source and designed a more protective case and added the outside-the-box mounts to the wooden frame. The first cooling tunnel I made was a full tunnel, but the motor plugs didn't fit well with the wall of the tunnel on that side, so I created a half-tunnel and half-top design for better access to other plugs. The air coming out of the vents during printing doesn't seem very warm, despite using TMC2208's in standalone mode. To utilize M3 screws for mounting the board, I added 3.7mm high spacers to ensure that the four M3x12mm screws extended the correct distance. I've included these spacers and an OpenSCAD file so you can easily adjust their height if you're using different length screws. Two M3x14mm screws were used to mount this case to the wooden frame, while two M3x10mm screws were used to attach the top fan mount to the case.
