[update 03/03/25: after using it for a bit, I removed the cross bar so that you can grab the mouse across the midline and not have to dodge around the large piece in the middle.]

[note: there's a LH (left handed) and RH (right handed) version of the model, they're just mirrors of each other. I find it's easier to grab and replace the wide side of the mouse rather than the narrow side but you do you. Also, the DPI/pairing button gets held down when the mouse is resting in the RH version, turn off the mouse when not in use.]

This is a wall holder I designed in onshape so I could store my trackball on a nearby wall when I wasn't using it. It assumes your wall is plumb and the bottom edge is approximately level. Supports are very much mandatory when printing this. There's a few messy inside corners that will be tricky to get the support out of but I've tried to be efficient with material usage. You might try splitting the lower longer arms into a separate glue-able part and that would greatly reduce the support needed, but that's up to you to figure out.

IMPORTANT: Make sure to tediously level the whole model to make sure the x-face has full contact with the print bed. Since I've designed the model with so many weird construction planes, it'll probably be a fraction of a degree off-level from the build plate and mysteriously fail as there's not full contact (ask me how I know).

My skill at surfacing is a bit garbage so the top curved surface of the mouse is a little bit off so if you design anything with the mockup, expect a few mm error on the top surface (bowed out a little more than the original).

Please don't be a jerk and try to sell this. Print it for your friends, do whatever, just don't be capitalist scum. I spent a few days designing this and mocking it up and am releasing it for free. You're just a bad person if you claim this is your design. I haven't watermarked it or anything.

I've held this to my wall with four screws direct into drywall and no anchors and it seems to hold okay.
