This started out as a remix of just the top of the 3 digit counter to allow it to work nicer with primarily the Prusa MMU3 in mind, and ended up combining parts from another remix and setting the (recommended troubleshooting) carry wheels at 95% scale all in one 3MF.
The STL is a bit hard to see, but at least in testing works correctly in PrusaSlicer for painting. The 3MF is likely better to use, and the interiors themselves are also available.
A full project or just the top is available.
The author remixed this model.
Made the D20 sides flush with the bed. Full project uses dials from Ghostracer.
