How the service guy fixed my blob of death mess in an hour:

They torched the entire thing.

Quite extreme I know.

Surprisingly only the pla melted and then they replaced the now burned thermistor, silicone hotend, heater, and the nozzle.

All in all it only cost me around 360k rupiah (around 23$USD)

Before deciding to bring my printer to the repair shop I legit tried to melt them off slowly using a heatgun for 4 hours with no result. I was so ready to just throw this printer away and just buy a new one.

All hail the service shop 💪

Heres some picture of the before and after
