Extruder Head Meltdown - Need Help

I'm hoping an experienced Prusa user can help me.  I got set up with an MK3S last summer and have done about 1,200 hours of printing since then.  Man I love this thing.  I recently left it to print a 3+ hour project and found this when I came back to check on it:

PETG Spaghetti Monster

I managed to extricate the solid blob from the underside of the head but it did a lot of damage.  Because it was a solid blob of semi-molten PETG, it melted the edges of cooling duct and welded itself to other printed parts of the head. The whole thing needs to be rebuilt but I can't print the parts.

Aftermath  

Is there some merciful person out there who would be willing to print a batch of new extruder head parts for me?  Hopefully with similar quality PETG Prusament or even ASA - to make it more temp resilient in the future?  I can definitely pay for shipping.  It has been this way for almost a month now because I've been too depressed about it to admit it's FUBAR.  My wife is a nurse and I'd love to try and print some of the face shields that were posted recently for coronavirus PPE but this is step 1. . .

Thanks for any ideas/help.

Hi Chris,

I'm in the UK and happy to help if you haven't got it resolved. I have some Orange PETG and can print the head parts for you. Just let me know which ones you need.

There are folks on Etsy and eBay that print the parts really cheap.
