Adapter to convert Ender 3 to direct drive with double geared extruder

thingiverse

This is an adapter to convert your Ender 3 to direct drive using almost all orginal parts. To be able to use my adapter, you have to print also this fang. https://www.thingiverse.com/thing:2718960 (The fang requires a bit of post production to be sure that the hot end can be firmly mounted with the original metal plate). Print with 4 walls to maximize the rigidity. Then you need an extension cable for nema motors, a m3x10 screw, a m3 washer. and around 70 mm of PTFE tubing. NOTE: Pancake (slim) nema motor does not have enough torque to work in this configuration. In the end a bit of patience to mount everything.
