A perfect working Prusa Mk4s with mmu3. The MMU3 has only been used a few times. All MMU3 parts are printed in Grey PETG with carbon fibre and so are the all coloured parts of the printer to match. I still have loads of spares and the original orange parts that are included. I have built a spool holder that I'm including in the sale for holding 5 filaments(See photos) The original spool holders have never been used and included also. This can be seen working before sale if required.
