Original notes

The original Prusa MK3S R4 extruder body has the bottom heatbreak opening 0.40 mm wider than the old MK3 (Ø22.8 vs Ø22.4 of the MK3).**In version 4x this is left as-is.

The neck tolerances are set to +0.1 mm, so the neck socket dimensions are 16.1 mm and 12.1 mm, providing a firmer grip of the heatbreak.
