Summary

My computer desk is not level, so my computer was being held level by a couple chunks of cardboard. Not the prettiest thing in the world. I designed these so that I could level my computer on my desk.

Added bonus, I now have enough space under the computer for my keyboard cover and a small tray to hold my SD card adapters.

The Base should be oriented right-side-up, and printed with supports touching build plate. 
The foot, will require a little finesse. I printed it at 100% scale in the Z axis, 95% scale in the X and Y axis and it's a good, clean, and tight thread. I didn't need to put in the set screws that I designed holes for. Depending on the tolerances and settings of your printer, you may need to scale the X and Y axes differently. Foot does not require supports if printed right-side-up.
