Keyboard/laptop wrist rest

Designed to be flush with a 13mm-tall laptop lip, this takes the pressure off. Can easily be scaled up or down to fit your laptop. I have mine held in place with a couple of loops of painter's tape underneath, removes clean without leaving a mess on my nice desk.

Print 2, one for each side of the mouse pad. Or scale it up lengthwise so a single piece is the full length of your laptop if you've got the build volume for it. Print settings really don't matter, just make sure it's nice and smooth on the top surface.
