The mouse shelf can be glued or screwed with m4 screws to the desk. Its meant for small mice. The space inside the cage is about 102mm x 65mm on the surface and 36mm in height. You can print either with the front side up as it is or maybe laying flat with support. I printed it with the front side up.

I 'am already planning a V2 with a hole to hold a cable at the back and/or a bearing mount at the top to make it turnable. So you could easily turn it around and add a cable for charging. Leave me a comment what you think about that.

Next thing will be also an keyboard shelf.
