I remixed XDr4g0nX's 1U Server Rack Cover Plate, as I wanted to use less material. So I removed the horizontal "flaps" on the top and bottom, of the parts. I also only bothered to do this with the un-vented blanks, as I didn't have a personal need for vented blanks since I'm striving to maintain optimal airflow, with only cold air coming in from the front, and hot air venting out the back.

If there's demand, I can also create larger blanks for 2U, 3U, etc.
