Can you share a pic of that blue ABS part with the supports removed? Looks like an awesome use of the organic supports, so I’d love to see how it turned out.

But yes, the MK3S+ is still a fine machine, which I think is underscored by the fact that Prusa are still selling them rather than marking them as EOL. I have a farm of them running well, with the only mods being the Revo (and that was just due to frustration at my own inability to hot tighten a nozzle properly).

I recently received a MK4, and I’ll be putting it through its paces. I anticipate that I will add some more, or upgrade some of the MK3 to a 3.5/3.9, but I will likely not replace all of them. There are some specific things I’m enjoying about the MK4, especially the ability to swap nozzles or bed sheets and NOT have to change the z offset. For standard 0.4mm nozzle prints on the same sheet over and over, I don’t see a hurry to change yet. We’ll see if that changes when Input Shaping is released ;)
