I designed my own closer tolerance version of the Miata eyeball vent with a 1" ball after having tried other people's designs and not being satisfied with the performance. This one fits in the tombstone hole exactly, doesn't rattle around, and is sturdy enough to hold a phone for track use.
As the vent is now fixed in orientation I've included both "x" and "+" versions. This is purely for aesthetics and both versions function identically.
Prints without supports as oriented (ball facing up). Brim ears may be required for the base of the column if your bed adhesion isn't the best though.
Pictured model was printed on an Elegoo CC in PETG with a 0.4mm nozzle, Arachne walls with 0.56mm default line width, 4 perimeters, 15% cubic infill, and 0.2mm base layer lines until 3/4 of the way up the ball, where it then flattens to 0.04mm for the tip of the ball.
Update: I've also added versions with a 16mm ball to fit the typical light-duty phone mount.
