Ender 3 Direct Drive! ”works with stock extruder fan house” by Blyckert
http://www.thingiverse.com/thing:3373107

I haven't printed or installed yet, but should allow you to set up FreeABL - the ultra cheap (free) ABL for Ender 3 by stevohen with a direct drive setup. Follow the guide from his thing (https://www.thingiverse.com/thing:3468254) for full instructions on setup/use.

Ok, I think this is all correct now. V3 fixes the orientation of the double position clip and reduces the side a bit to reduce plastic usage. Should be a bolt on replacement using the stock screws and the stock fan cover.

Update: Finally printed and installed. Fits well. Screw holes may be a bit snug on the heads. Added a "clip" to help guide cables away from the extruder wheel. Next up will be a cable clip/guide to go where the extruder mounted stock.

V4 with integrated cable guide....

Added a customized Gcode startup file for Cura...
