===Initial Tray Design===

Here is our initial tray design. We came up with this design while trying to figure out how to create more space between each individual tubes so caps don't interfere with one another. Our solution was to create this collapsible tray that will allow the tubes to be on different levels so they will be further from one another. This also allows the tray to fold completely in order to take up less room in a lab allows for easier storage. Necessary modifications will be made in order to create more stable stands.

Features: Creates more space between caps because of different levels, has a collapsibility feature

Issues: Collapsibility not really necessary, too unstable, not worth manufacturing.
