This is just the board, not the pieces.
When you have these designs cut you need to order it in 4.5mm acrylic in size 3 sheets and have cut both "Board3" and "Board2" to have a complete set of parts.
Be aware the design as it is may be a bit hard to put together. Some sanding on the inside of the joints should make them be a bit looser. DO NOT force them together.
It will cost about 140 dollars to have this cut without Ponoko prime.
