I was tempted to do it, but I got my 3s tuned where it produces parts I'm happy with and largely trust the 1st layer, building a Voron v2 instead (also to get a larger print area) and keeping the 3s as a known good reliable printer, likely to be what I'll use for abrasive filaments as I've already got it setup for that.

I'd love if prusa put out component only kits tbh, I've reprinted everything in abs/Asa as I do a lot of abs printing and had the original petg X axis idler fail on me so I'd really like to have the option to provide my own printed parts, or even being able to choose material types. Working on putting a SMuFF together instead of grabbing an mmu3 for partly that reason.
