Tight Dust Protector for Prusa MK3/MK4

Made the threaded rod hole tighter (8.5mm) and added cutouts on the side for easier removal with a nail or screwdriver. There are files for 2mm and for 1.5mm tall cutouts, both worked great in my testing, just depends what you want. You may need to scale this up so it fits better in the Z-axis motor holder, you want it a bit tight but not too tight (101.2% worked for me). Do not scale this down, there's a high chance your threaded rod will touch if the hole gets smaller.
