Introduction
Challenges
Static structures are not sufficient for reproducing most useful objects.
Approaches
Bearings allow frames a variety of motion in relation to each other and other components.
Linear Bearings
To use the captive hex holes, insert bolts from the inside of the linear bearing, pointing out toward the frame.
