This is a remix of https://www.thingiverse.com/thing:4688916
This remix supports MMU printing, so no more letters falling out or gluing your fingers to the models.
I sliced the model in PrusaSlicer 2.4.0-beta3, which reports mesh issues. However, slicing and printing is successful. If you're running Windows (which I'm not) then you can right click on the model or error icons and select the option to repair via NetFabb.
The author remixed this model.
