I ordered one of their Classic models a few weeks ago, it should be here Monday. (They just moved warehouses, so my order was delayed.) I'm really excited for it! The trackball uses QMK firmware (https://qmk.fm), which is mostly known for powering open-source mechanical keyboards. Customizing it is a breeze, and it's got a whole lot of great functionality built-in too! One of the big things that pushed me to Ploopy is the use of roller bearings, although now I see there's a ball-transfer-unit mod which is basically the ideal form of bearing for this: https://github.com/ploopyco/classic-trackball/tree/master/ha...
In Ploopy open source thumb trackball
I was looking through the repos for the Classic Trackball, too, but found the design files and was kinda impressed that also the PCB files were open [1]. They contain the Altium Designer files in that case. The only thing why I'm probably not going for it is that 1) shipment would be way too much to justify and 2) the STLs seem to be 3d printed instead of injection molded or similar, so the "no cheap shit" argument on their website is kinda different for me if I have to print all files myself anyways.
