ZSA Navigator Trackball Crown

The Navigator Trackball is ultra-smooth, up there with the best trackballs, when using your board flat or at a slight angle. This print lets you continue using the Trackball even at higher tenting angles.

You won't need any supports or special settings in your slicer. Just plop it in and print. It will slide right over the top of your Navigator Trackball (with the ball already resting in the core) and hold it down. You don't have to unscrew anything, and you can just slide it off to remove.

A few notes on fit

• The crown is friction fit, so it can still slide off if you whip the board around too aggressively, but as long as you're using the board and Navigator normally, it should hold fine. If it does slide off, that might be a sign to be gentler with your expensive keyboard. 🙂

• Using this print means there will be more points of contact on the ball. It is designed to keep the ball feeling as smooth as possible, but it still won't feel quite as smooth as it would without the crown.

• The intended fit has the bottom of the downward arcs of the crown and the downward arcs of the Navigator core meeting at the bottom — basically the shapes of the crown and the core should be aligned. You can, however, adjust this slightly if you want a different feel. Push it a little farther down onto the core for a tighter grip on the ball or not quite as far for a looser fit. Just make sure the crown is pushed down enough to hold before moving the board around.

Many thanks to Voyager user Joseph Lee for inspiration for this design!
