Skree Splitball

The Splitball solves almost every problem trackballs have in custom keyboards.

Most 3D-printed cups work… sometimes. Tracking suffers when the bearing surfaces aren't exactly where they need to be, and your sensor wants a 2.4 mm gap between the ball and the sensor. Getting that right is hard, especially when the cup is built into the case.

The Splitball is printed in highly accurate resin, in the ideal orientation. It uses 3 ceramic balls, positioned with grub screws, so you can fine-tune the ball-to-sensor distance. The balls aren't rigidly captured, so they come out for cleaning. Bolt it to your case (Cosmos Splitball trackball module).

Compatible with the PMW3610, PMW3389, and PAW3395 sensor boards.
