The Original version by The_Doc didn't fit on my Ender 3. turns out the updated Ender 3 has the extruder about 4mm further away from the Z screw than before, so i remade it to fit.

Edit: 01/02/2020 Ive uploaded a corrected version that the bowden tube fitting will actually screw into. the inner diameter of the hole on the original was too big. it has been fixed and tested.

Visual measurement of the incompatibility of the original part and measuring the original part in 123D design, I was able to reconstruct a similar part from scratch (as i could not properly edit the original) that fits the newer design.
