Stick with a regular mousepad.

Probably not worth it. A 3D printed pattern sounds cool, but in practice, the tracking can be inconsistent and the feel is often rough.

The problem is that 3D printing creates tiny ridges and irregularities that can throw off optical sensors depending on the pattern and printer quality. Some surfaces work fine, but you’re gambling on something that might feel like sandpaper under your wrist. A good cloth pad is smooth, predictable, and costs less.

If you really want a hard surface, get a plastic or aluminum pad. The 3D printed version is solving a problem nobody has.
