Modified Flexible Filament Extruder Upgrade
thingiverse
This is a remix of joshvv's Extruder Upgrade. Should work for Creality CR-7, CR-10, Ender 2, Ender 3, and Afinibot A5, A31. I just made the hole for the PTFE tube longer to go through to the coupler. His upgrade did not work for me, with my modification there is no space left where filament can bend or get stuck. I have printed the big chainmail from (https://www.thingiverse.com/thing:3096598) FLOWALISTIK in TPU with my version of the upgrade without any problems. Just follow his instructions for the installation: https://www.thingiverse.com/thing:2144277
