If you're fairly handy, here's one I made myself
(glued & screwed)
The hole in the bottom is for the cooling fan. The hole in the back is for the vent, positioned so the fan draws the air across the compressor.
The vent in the back is actually a dryer vent and I zip-tied a screen in the bottom of it to keep critters out.
Up and running for 2 years now, nearly 24/7, just replacing the exhaust filter about every 3 months.
If you have any questions please let me know.
