I have to laser out lots of small little shapes. Ovals, stars, squares, rectangles, irregular polygons, and more. I save all of these in a drawer in case I need to accent something.

This is for a 6x9" bubbler mailer filled of my greeblie-like parts from this drawer. Drawn at random. You'll get quite the variety! There will likely be a mix of 1/8" acrylic (in various colors), 1/8" veneered plywood (walnut, cherry, maple), hardwood, 1/4" veneered plywood, and even some cardboard.

Per Wikipedia: "Greebles, also greeblies (singular: greebly),^[1] or "nurnies", are parts harvested from plastic modeling kits to be applied to an original model as a detail element. The practice of using parts in this manner is called "kitbashing".^[2]"
