Alfawise U20 Bowden extruder update for TPU printing

I have a 3D Printer Alfawise U20. I tried to print few objects using TPU filament. Unfortunately, all my prints were failing because the filament was moving around the cog-wheel.
I finally designed and printed an updated version of the extruder piece which allows to drastically reduce the space between the exit of the cog-wheel and the entry of the hole.

And it works ! No more fail printing with TPU.

I uploaded the F3D file if you want to perform your own updates.
