Upgrade for Cowtech 3D Scanner: Laser Holders and Rotative Plate

If any suggestions, feel free to write. By the way, this 99$ scanner ended up to cost an additional 30$ + 38$ for shipping and broker/tx fees, just saying.

Upgrade 1:
New rotative bearing holder plate with direct drive to increase the angular position accuracy. Simply install the bearing in the new part and press fit the center hole in the motor shaft. There is a flat side in the plastic part center hole to match the motor shaft flat side... So align it. Tested and much, much better.
