We utilized the TIW's 3D printers to make our can-holder. The key to this design is the tolerance between the can and the holder, as we needed to make room for rubber stripping that prevents the can from rotating our slipping when the tab is lifted.

Since our mechanism is being held up vertically by 2 acrylic sheets, we created lower support pieces that we stacked so that the mechanism would not have the risk of falling.

Electronics:
For electronics, our mechanism is powered with a AC to 12V DC power supply that fits the needs for the motor we are using. We controlled the motor using L298N motor driver and pushing code to activate the motor using and Arduino.

For our software, we needed the motor to run continuously, so we developed at Arduino code that turn turns on the motor at highest speed for a long time so that multiple cycles of the position profile can be made.
