DIY Follow Focus Created with K’NEX

Update on 12/9/21: This video has been taken down by the creator.

YouTube user Prippman created this nifty follow focus using pieces of a K’NEX construction toy set and a $5.50 K’NEX battery power pack (that’s even cheaper than the $6 DIY handle we featured yesterday). The resulting system can be used either manually or with the help of the motor pack. Three cheers for ghetto gear!
