The manufacturing and assembly of the machine primarily consisted of two distinct parts, being the mechanism's wooden frame and the actual linkage itself.
Wooden Frame
For the wooden frame, the design was initially assembled within SolidWorks with the dimensions of the reusable plastic bag kept in mind. The wooden frame needed to be large enough to host the bag, gear, axles, and other elements of the machine inside of it, but small enough in order for these elements to be close enough within the frame to interact with one another while also not being too costly of an investment. The following CAD sketches for the wooden frame can be seen below:
Figure 4.1: CAD drawings of each of the four types of wooden walls for the frame, consisting of (starting from the top left, moving clockwise) the back wall, the frame base, the side wall (printed twice, one for each side), and the motor wall
Figure 4.2: In-application CAD image of how the wooden frame would be constructed
For the actual construction of the wooden frame, the different wood shapes were laser cut out of a larger sheet of wood, then glued together using wood glue.
Bar Linkage
last thing that needs to be done - might also need more images of the sliders attached to the inside of the box if possible
