20A Fanless PSU + Dual MOSFET Case with Fused Power Inlet Switch Module and bracket (FLSun i3 and others)
thingiverse
I actually quite like the 20A PSU, no loud little fan and it's easy to add a large quiet one to keep it cool, it's been almost a year and it has not given me any trouble so far, even cranked up a bit. I highly recommend checking out JamesK1 for the original design. I made some key modifications including changing the standoff layout to accommodate two smaller and cheaper 50mmx60mm MOSFET boards, added hooks for better wire management, rounded the power wire outlet hole for a grommet or strain relief, and added optional mounting brackets. I also optimized the walls to be a bit thinner and improved the fit on the PSU for a snugger seal. If you decide to build it, please share your project with others!
