doomsey_162111's "MMU3 Alternate cassette" design but updated with the R4 version for MK4/S/Core One compatibility. R4 version of the cartridges sits further out as the MK4 extruder design requires more filament to be unloaded.
- M3 x 6mm (socket head cap) for bearing shaft instead of 2.9x8.5mm shaft
- 6mm "UM2" 4mm ID collet instead of the smaller 5mm "E3D" collet
