Initially, we hoped to 3D print only the fingertip and palm base of the hand (Links 1 and 6), and use laser-cut wooden pieces as the rest of the links. However, upon assembly, we realized we failed to account for the disparity between the listed thickness of the wood and the actual thickness. We found that there was no sold thickness of wood that matched, and so we opted to switch to 3D printing so as to not have to manually change the thickness of each piece in CAD. Despite this failure, it was still a worthwhile incident because we were able to roughly assemble the pieces and see that the mechanism did indeed work.
