As my trays keep stocking up, I wanted to add more stability to the shelves and to keep them together.

I designed this to keep the same criteria from the original design (Expandable, Fast Printing with minimal materials, Keep the trays secured)

Its just a simple tray that will interlock with each other and with the original shelving tray.

Note:

• This will need to be printed with support.
• You only need this if you have more than one tower.
• Print only one of (Left side) and (Right side) each are marked with L & R respectively.
• If you have more than two towers you will need to print (Central piece) marked with C, for as many as you need.
