Anycubic 4Max Pro PTFE cutter

thingiverse

A cutting tool for the short PTFE tube in the Anycubic 4Max Pro hotend. The original PTFE tube in my printer was too short and caused the filament to collect in the gap between the nozzle and the PTFE tube. Cutting a new piece helped a lot. However, you still need to check it regularly, because the tube shrinks a bit with time due to the high temperature. This tool lets you to easily and precisely cut the PTFE tube to the required length. Insert the radiator into the tool, then insert the PTFE tube all the way into the heatbreak and use a sharp knife to cut the PTFE to size.
