Buck Converter Mount for 4020 Fan

thingiverse

I needed to replace some of the fans on my Ender 3 v2 with quieter Noctua fans, but those are 12v fans, and my Ender runs on 24v. To get around this, i got some cheap Buck converters, but had nowhere to install them. I designed this simple clip to stack with a 40mm fan (30mm thick) to hold the converter, allowing me to wire them very close to the fans themselves. I used [these Buck converters](https://www.amazon.com/dp/B07VVXF7YX?psc=1&ref=ppx_yo2_dt_b_product_details), but any similarly sized converter should work. The screw holes are designed for M2 x 8mm screws, but any M2, down to about 4mm will work. I just threaded the holes with the screws themselves.
