Printed parts - infill % - 15% or 20%?
I am waiting on a response from Support in relation to clarification:
Assembly manual and Prusa's general article in their Knowledge Base each suggest to use 20% grid infill for any printed parts.
Notes on the Printables for the MMU3 printed parts (as well as for MK4 printed parts), mention to use 15% grid infill.
It probably doesn't make that much difference to the overall strength of the part but it would be good to understand what is the correct official recommendation.
RE: Printed parts - infill % - 15% or 20%?
Notwithstanding the gcode files supplied by Prusa are based on 15% infill, (also referenced in the details on Printables), Support have advised that parts printed and supplied by Prusa from their factory are done with 20% infill.
It doesn't really matter given only a small difference but there should only be one recommended set of parameters.

Can you put here the refference links?
RE: Printed parts - infill % - 15% or 20%?
I used 15% infill, both grid (recommended) and honeycomb. It's not terribly important
Also printed on a 0.6mm nozzle with 3-5 perimeters. External perimeters first checked.
Everything is functional and from what I've read/experienced perimeters have a lot more to do with strength than infill.
Dimensionally accurate parts are far more important. The parts are designed to print without supports which requires very good overhang performance.

@3Doxle -
Did your ⌀0.6mm-nozzle-printed parts assemble well? I have the 0.25mm nozzle equipped and could handle the tradeoff of time for quality, but I am concerned about tolerances and things not fitting as a result. I am hesitant to swap nozzles too.
0.25mm would look very clean.
