These parts are based on the Original Prusa i3 MK3/s parts, they've been modified to fit the E3D - Volcano hotend. Modifications include
I lifted the body 8.5mm to account for increased hotend height. (no firmware change required for z-heights)
Adjusted cable paths on a few parts to account for new wiring path.
Increased volume in wiring channel to allow for a silicone wire upgrade.
Designed new part fan shroud.
Lowered P.I.N.D.A probe mount accordingly.
Adjusted Cable holder to accommodate wiring change.
I am using this current version on my own printer and its been working great for over a month now, if you are unable to print this mod I am also selling them on these sites
