Printed one in black PLA at .2 with 105% extruding and it came out perfect. A bit tight fit and requiered some sanding but now it is perfect.
Great when changing filament and you ned to extrude until the color of the new filament comes out clear.
Posted a make to show how it look on the printer

You're aware that spinning the motor by hand turns the motor in generator producing a current that may damage the board? May I suggest you to add a warning in your description, both as a disclaimer should someone fry their printer with your invention, and for people to at least taking care to spin the motor with care and slowly to minimize the risk.

Yes I am aware that it can damage the board if you turn it to fast. I'll add a disclaimer as soon as possible.

After 2 weeks of use, the piece turns in a vacuum. I had to strengthen it with a small metal strip in the flat side of the hole

I have not had this issue.

What does turn in a vacuum mean? This also hasn’t been up for 2 weeks.

the flat side in the hole wears out and when I turn the knob, the extruder does not follow the rotation movement
