Keyboard wrist rest

I was looking for a simple wrist rest for my mechanical keyboard and could not find one on thingiverse; I'm guessing because they were too big to fit on most build plates. So, I designed a simple rest by looking at a few pictures of wrist rests online and then split it in half using a simple finger joint cut.

Honestly I was expecting this to just be a mk1, but the tolerances were so tight that it fit together well and didn't need any sort of glue or joint redesign to make it do the job. I'm sure someone can improve the joint design so I included the uncut version as well. Something like this would probably do well with some rubber feet as well to keep it from sliding around.
