V-Baby 20 Tooth Worm Gear Box

I found the enclosed worm gear box spec'd for the stock V-Baby to be defective and the seller of the product doesn't seem to know the meaning of "customer service." So I found a 20T 20:1 ratio solution similar to the V-King and re-mixed the V-King part to produce this.

I've been printing with it very successfully now for a couple of weeks.
