Printer 3 is repaired and back to service.
Hot end sadly went out in a blaze of glory so I installed the spare in the parts box. Test print ran fine.
I attempted to replace the temp sensor in the old extruder head in the parts box so there would be a spare, but it appears to be less serviceable than hoped. There is a spare extruder nozzle and misc parts.
There are now no good spare fans or nozzles in back stock.
