Upgraded my Adept trackball to use the AnyBall 57-68mm mod, with an Aramith tournament series cue ball and Rexroth BTUs.

Sorry for constantly proselytizing about the wonders of PHA lol. But look at this thing! The Adept is pretty ingeniously designed for printing, but I wouldn't really say it's an easy print either. There are steeeeep overhangs and really long bridges. After getting the settings dialed in, PHA more or less handled it just fine, and now my trackball is home compostable. It also has this really interesting feel to it, kind of reminds me more of leather than plastic.
