Flap Sorting Box
One of the more tedious parts of assembling a split flap display is getting the flaps sorted and ready to be inserted into the drum. This sorting box (of which you'll need two) come in quite handy: They make it easy to place and remove flaps from it, and you can also put them on a piece of paper with the correct flap order to help with sorting.
