Sovol SV01 board fan and step down converter holder (Updated 80mm)

thingiverse

This is a new version of my board fan and stepdown converter holder:https://www.thingiverse.com/thing:4627013. In contrast to the first version, it has the following changes: - using a 80mm fan instead of 70mm - It has an air deflector ("spoiler") that directs some airflow under the board - it is 2mm less high When using a board with soldered TMC drivers (like the SKR MINI E3), most of the heat is given off to the copper and the PCB, so some minimal airflow below the board helps cooling. To acomplish this, I use a bigger 80mm fan that stands over the lower edge of the board and an air deflector ("spoiler") that redirects some air under the board. Except for the need of a new base plate with openings for the fan, this holder is non-invasive, this means that it is mounted on the existing screw sockets. I used an old cabinet back board as base plate and sawed openings for the board and PSU fan into it. The fan inside the MeanWell LRS-350-24 power supply is also very loud because there are no air holes for it in the base plate. This causes the warm air to build up and so the temperature controlled fan is running longer and more often than needed. I recommend to make an opening for it in the base plate and modify or exchange this fan also. Either by simply exchanging the 60mm/12V fan with a silent one or by replacing the cover with a cover for a bigger fan - I use this one: https://www.thingiverse.com/thing:4082992 This is a 80x80x10mm fan that is flat enough to fit inside the case (I use it for board and PSU): https://www.aliexpress.com/item/32570285568.html Edit: You can also use a more common 80x80x15mm fan but then it reaches a bit above the base plate. But it is still enough headroom for the fan to suck air (around 1/2cm I guess). OpenSCAD files included, feel free to modify.
