So, I use a volcano hotend on my MK3S Prusa Bear machine for years and decided to do some maintenance. I saw that my R4 extruder cover was melted. It also affected the (R4) extruder body, as the PINDA mounts was bend causing calibration problems.

After a little research I saw Prusa had upgraded the cover and body parts to R5 by having thicker walls (https://www.printables.com/model/88272-i3-mk3s-printable-parts). I decided to apply this also to the modded extruder cover from https://www.thingiverse.com/thing:3507197

I did this in a quick and dirty way and didn't even take the effort to update de R4 text, but it fits perfectly now.

Only extruder-cover-r5-volcano.stl was made by me. I added the rest of the parts from the original design to make it complete.

Slice and print directions

  • When you orient it with the fan-side down and use a small layer height (eg 0.12 or less) you can print it with minimal tree supports. This makes the front-side look better (see screenshot)
  • Print the cover and fan support in PETG. ABS from me was to brittle.
  • Print the shroud in ABS, use a small layer height and some tree support to get it right.

Please like if you appreciate this.
