This is a pretty loose design, I just added as many bees as I could to a 600 x 900 sheet (this is the ply dimensions we use in our laser cutters) and added some hanger bars to make a mobile. There's a large and a small centred one, and another with a 1/3 offset so you can make your mobile asymmetrical. The attached files are the same thing but in different formats, so you don't need to download all of them. Have fun assembling your bees! Or better still, get the kids to assemble them and paint them cool colours as a fun activity over the Easter holidays.
