direct drive extruder mount. Ender 3

UPDATE 2: Been using this for a good few hours now, currently have my retraction length to 0.4mm retract speed 30mm/s :). If you have extrusion issues check length of ptfe tube is correct.

Currently just printed another revised version, shorter and also working on modding the original extruder to remove the bowden connector and have the filement path fully supported

UPDATE: Fixed problem with couplers not aligning.Use the file named
CE3_direct_drive_v1.1.stl

I printed the original off
