Ender 3 cable chain hot-end mount for small chain

This model is based on a model on Thingiverse. However, even if it looks very similar in shape and size, the desing is a redraw of the original idea for my other project with different chain size. This adapter perfectly fits on Ender 3 Neo V2 head without any special modification. https://www.thingiverse.com/thing:4314829 

Instructions: 

Print out the part in the way you wish. But, keep in mind that some tearing force could happen on this part, therefore PETG or more tearing resistance PLA+ would be needed. The model is not sensitive to layer height settings, so you can print it even in a fast way. When you have the printed part, remove the head cover screw that fix the head cover from back side of the head. Replace it with an M3 x 15mm screw when fixing this model in place. When you attach it to the hotend, please double check for perfect and easy head movement. The gap between the rubber gear and the model should not less than 1.5mm. If you print it correctly, this will not happen of course.
