Mac Keyboard Riser

This keyboard riser lifts a standard Apple Keyboard a little over 1cm to maintain typing angles when using a cushioned wrist rest.

I found that other risers change the angles that make this keyboard comfortable to use, so I'm sharing my solution.

13mm x 3mm recesses in the bottom allow for use of most medium size cabinet door cushions for grip. Anything about 4mm tall should be perfect.
