The assignment from my son was a dragonfly that was also a shelf. What he got was more dragonfly than shelf.
It's not shown here, but I later replaced the painted wooden shelf with a 3/16" steel plate of the same size.
Materials: brass & malleable black iron pipe, copper gas manifolds, copper wire fairy lights, drip-feed oiler from a hit-miss engine (a real thing, and an interesting rabbit hole if you search it), chandelier sockets and crystals, and a lot of current switching. The fairy lights in the tail are 3.7v DC, the eyes are 12v DC, and the candelabra bulbs are 120v AC.
