Custom stepper holder for V400. It doesn't make contact with the shaft and the bearing on it, as it's main reason for increased ringing artefacts and noise levels.
Print in PETG, ABS or ASA. Min 40% infill.
I recommend replacing the stock cork damperers that are between the holder and the stepper motor with silicone ones:

Also use M3 washers and little bit of thread locker or nail polish on the screws that are holding the motor to the holder, and the vibrations tend to unscrew them over time and they get loose (general issue, not related to the holder).
With this holder, you can use different stepper motors, e.g. LDO 42sth60-2004mah, that improved printing accuracy and decreases nozzle scratching the model significantly (tested)
Edit: If you replace stepper motors, you need also new pulleys - 5mm shaft, 20 teeth, 10mm width:
