Had a few messages on what I used to power the cabinet as well as the LED and fans. This is what I used and it has worked well.

I wanted a filter to fit what I needed on my in progress IKEA Lack Prusa enclosure. I plan on mounting this to the top of the enclosure to help cool and clean any ABS or other fumes. I will post some follow ups once the enclosure is done and the MK2S arrives.

Holes are 3mm threaded, I used a grommet I had laying around not sure what you will needs depends on what fan you use as well. But home depot is a good source for different sizes and needs. The fan pushes a ton of air but the HEPA filter slows the air flow down a great deal; I might just opt for a carbon filter mesh and cut it to size. The filter is press fit, the fan is as well and doesn't require any fasteners- there is a stop on the inside for the fan to bottom out against as well.

Print time: took about 12-13 hours for the main body and 1-2 hours each for the grills. However I printed mine at .15 with a 15% infill on the X-One.

Inspiration for enclosure came from http://www.thingiverse.com/thing:2150826 also the fan shrouds it included. Good work all the way around.
