Anet A8 PSU Switch Cover

thingiverse

I'm building a PSU switch cover that doesn't require any drilling on one side. It has a small piece that fits into one of the existing holes on the PSU. My goal was to cool the PSU without adding a fan directly onto it, so I added a ventilation slot to the cover instead. With the bottom of the cover closed, air flows upwards into the PSU and works effectively. I intentionally left it open to the option of adding a fan later if desired. To do this, simply drill holes and use screws as needed. I found that printing it upright with supports produced the best results.
