For the last few pushes of this project, I needed to find a way for the lid itself to latch onto the can. To do this, I worked through a process of trial and error in cutting very thin circles of acrylic that would make a perfect ring around the edges of the top of the can. This was a bit trickier because I needed to create a ring that was not too thick so that it could easily latch on to the can and not too thin so that it wouldn't snap with too much pressure. 

After several iterations, I finally found the right size and glued it onto the base of the shoulder piece. For the final step, I measured the inside circumference of the neck piece and created six small circles that would snuggly fit as an acrylic cork, completing my final product.
