Sovol SV01 board fan and step down converter holder

thingiverse

This is a non-invasive mount for a board fan and two step-down-converters (needed for 12V fans and lower voltages) in the Sovol SV01. Note that on the pictures the build was not finished (some wiring, cable management and the second step-down still missing). But as you can see in one picture, the slim fan does fit into the case, so you don't need to raise the feet. You just need to make a new housing cover with the corresponding opening for the fan. The used fan is this cheap 70x70x10mm fan (driven with 8-9V it is very quiet while still cooling enough): https://www.pollin.de/p/axialluefter-y-s-tech-fd127010lb-70x70x10-mm-12-v-320452 The step-down converters are this common LM2596 parts: https://www.aliexpress.com/item/32721507753.html To avoid the need for support, it consists of two parts that will be screwed together with three M3x12 screws. The fan also screwed with four M3x8 screws. The base is mounted in the case with two M3x5 screws on the existing screw-sockets of the case. The part is my fist try with this great Round-Anything library that makes creating rounded parts in OpenSCAD easier: https://github.com/Irev-Dev/Round-Anything OpenSCAD files included, feel free to modify or improve. EDIT: This version worked perfectly when printed on my Ender 3. But now I printed it again on the Sovol SV01 itself and it turns out that some fits were too tight and therefore difficult to mount. So here is an improved "v4" version (the lighter gray on the pictures) that has more clearance, is more robust and holds the fan more in the center of the board. Update 29.10.2020: I made a new version of the holder with a 80mm fan and an air deflector that redirects some air below the board: https://www.thingiverse.com/thing:4637905
