BFTB design: Z axis wobble, lead screws and bearing blocks

This series of videos explain the design choices, experiments, research and theory behind the design choices and trade-offs I made when designing the 'bang for the buck' live stream printer. This particular video is an overview of the lead screw arrangement for the Z-axis. I will be covering the Z-axis as a whole in a future video. Of course, this is all subjective, but I tried to include enough theory, history, and experimentation to make the video informative as well. Feel free to post your own experiences and design choices in the comments below.
