Hi! In case you also have the MMU2S to MMU3 upgrade kit, you can continue from the chapter 4. Idler assembly. - and just use the basic components from the MMU2S kit.
The MMU2S kit alone will miss some of the important components for the MMU3 such as the Idler coupler, ferromagnetic ball for the selector, magnet for the selector, 2.5mm ID PTFE tubes, Collets etc. This is why you need to either get the MMU2S to MMU3 kit, or source the missing components yourself.
