Bigtreetech SKR 1.3/1.4 mounting bracket for Sovol 3D SV01 UPDATE: v2

thingiverse

Update 2020-03-13 Cooling tunnel is completed. I'm skipping the MOS-FET part for now. It's designed to accommodate a 40x40x10mm fan like the Noctua A4x10 FLX. The lid can be fully closed and optionally modified for increased fresh air intake, but this isn't necessary in my opinion. The mount next to the fan is intended for a StepDown-Converter. However, I cannot guarantee that every StepDown-Converter will fit these mounts. I used the LM2596S to step down to 12V. Version 2 SKR 1.4 will follow soon but I'll have to modify the mounting distances a little bit. The difference between 1.4 and 1.3 versions is about .2mm which could be within the tolerances. The tunnel, however, needs some additional cutouts on the left for an additional fan header. Maybe this isn't an issue. You tell me. I don't have an 1.4 board to take measurements. I'm using this as a mounting bracket for my BigTreeTech SKR 1.3 board. You'll have to modify your enclosure anyway for it to fit. I had to cut off the stock standoffs and the mini USB port opening must be cut wider to fit the full width USB-B port of the SKR 1.3. A version for the SKR 1.4 with slightly different dimensions on the mounting holes is included as well. I drilled four 3,5mm holes in the enclosure matching the bores. And used M3x16 screws with nuts and washers to mount it properly. For the fan and the board you can use the stock screws from the original board if you want to. This bracket is inspired by Franks 3D Shop's version but built from scratch so the motherboard fan is aligned with the mounted stepper drivers. Also, unlike Frank's warning, my screws holding the power supply were long enough, and an insulation layer was added below the PCB. So nothing hazardous on my side here. I'm currently working on it as my spare time allows it. I'm planning on adding a tunnel blowing above the stepper drivers maybe with a Noctua 4010 silent fan as well as a mounting position for a mosfet driving the heat bed. Because the heated bed is (officially) too powerful to be driven by the SKR directly (at least the manual states this.)
