Damaged hot-end
During an overnight print, the Y axis belt on my i3 mk2S failed. The print continued and filament from the extruder coagulated into a huge blob encapsulating large portions of the extruder assembly. The blob is now solidified and cannot be removed without destroying the hot-end wires and plastic housing. It is likely that the extruder assembly and all associated components will need to be replaced. For example, even though I could detach the extruder motor and PINDA probe, their wires will be damaged during extraction.
I can't find these replacement parts on the Prusa e-Store. Even if they were available, it may be more cost effective to order a new printer kit.
So here's the question: Is it sufficient to order an i3 mk3 upgrade ($499)? Will this include all necessary components to fully replace the hot-end assembly on my i3 mk2S? Or, should I order another i3 mk2S ($599) and scrap my existing unit?

You can contact support via the shop.prusa3d.com site. They do keep replacements for everything, just some they do not list and only keep for problems like yours.

Also, I believe Ultimachine.com has those parts as well
Re: Damaged hot-end
Thank you for responding. I will contact Prusa support to request a repair parts quotation.
Re: Damaged hot-end
I've disassembled as much of the extruder assembly as possible. Attached are additional images of the damaged items. By my reckoning, I will need to replace the E3D V6.1 Assembled Hotend and the ABS parts which encapsulate it.
