MMU3 with MK3S+

Will the MMU3 that's available on the Prusa site work with my MK3S+? Its only showing MK4S and MK3.9S as options.

RE: MMU3 with MK3S+

I can't say about buying it new, but I can say that I bought an MMU2 and upgraded it to an MMU2S then an MMU3, and it works with my MK3S+.

I did some quick searching and found this post by Josef on Instagram.

It looks like the stopped selling it. But you might be able to get the kit for the 4/3.9 and then add some parts from the parts store to your order. Good luck.
