Costume Power Lights

thingiverse

My kid is rocking a video game character for Halloween and wants green power lights shooting out of his sleeves. To make that happen, I grabbed two cheap battery-powered 20 LED holiday light strings. Printing a bracelet with spiral sides and no top or bottom was the way to go, so I printed it solid, except for the collar and clasp. Using a raft made sense since the surfaces are thin and could come loose from the print bed. Starting at one end of the bracelet, I threaded the light string through the tube until it emerged on the other side. Then, I continued threading lights through the tubes until I reached the opposite end. The battery pack slips into the square loop on the collar and gets taped in place. Putting the bracelet around my kid's wrist was a breeze, then slipping the collar over the bracelet with the opening on the opposite side worked like a charm. Finally, snapping the clasp over the round ends of the collar sealed the deal. With a flip of the switch, we were ready to take down galactic evil-doers. The post-Halloween report card is in: bracelets worked perfectly, the clasp stayed put, and my kid said wearing them was no big deal. He even called them the best part of his costume – that's a success in my book!
