Shaker Holder
We decided to 3D-print the holder because of the complicated shape. The hole seen at the bottom of the holder is where a shaft connects the holder to the end of the linkage. To test how well the holder worked, we vigorously shook the holder with the shaker inside to mimic the worst-case scenario.

When attaching the shaker holder to the linkage our team found that we did not make a long enough base plate. To solve this problem we glued wood to the bottom of the shaker holder to make sure the bottom of the holder make contact with the bearings.

Stand Assembly
We glued the pieces of the stand together because it was easier than taping holes for screws when the wood is thin. To keep the linkage plate in place and in line with the cam we had to add wooden spacers. We also had to add tape on the left of the base as seen in the picture below because the linkage plate would go too far to the left and fall over.

Electronics
The motors were attached directly to the linkage plate and stand using screws. We then connected each motor directly to a battery.
