Hi, I have an ultimaker original plus that has something PLA filament stuck in the hot end isolator coupler and hot end isolator tube. I tried heating it up using the heating block. I tried soaking it in boiling water. I tried dripping some acetone into it but I can't get it unstuck. I'm in the US and I can't find any replacement parts that will ship to my location. Is there something else I can do or place I can find a replacement part? Thanks, Audrey
