Creality CR-10/Ender 2/Ender 3/Ender 4 Extended Extruder Arm with PTFE Reinforced

This thing is now obsolete, instead use https://www.thingiverse.com/thing:3136000.

Really liked the original model but it kept breaking for me due to high loads on the bearing screw from the spring. This remixed model removes this failure point (also broke my original extruder arm this way) by holding the bearing between two plastic arms. I also reworked the PTFE tube hole to allow the PTFE tube to extend all the way to the extruder gear.

You need to use a longer screw to hold the bearing,
