Extruder for Cr-10 Smart.

Replacement extruder for the Cr-10 Smart. It requires screws, filament bearing and ptfe tube holder, from the original extruder. I made this because the original one broke. I printed it with petg, 4 walls, grid infill, 20%. My printer can print the tensioner M5 screw, hope yours can too. Lubrication helps. Kitchen oil works fine. It is in the position i printed them, used support only where touching the bed.
