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 and part of the model was in contact with one of the wheels on the x axis and my pc4-m6 coupler was too long and also the original hotend fan would not fit, it now does :). I changed the screw holes into slots for adjustment to accomadate the bigger coupler and made more clearance for the wheel. Printed mine in 10% infill seems like enough you may want to go higher. Edit: Forgot to add you will need m3 screws.
