Lung Test Prank
thingiverse
I love a harmless pranks and have wanted my own Lung Test prank after watching videos. Works perfectly as intended. I used a ball bearing from an old fidget spinner and glued the parts together with poly cement. A coat of paint to make it look a bit aged and I have had lots of fun I liked the idea of JFK1990's design and decided to remix with a nautical theme. https://www.thingiverse.com/thing:3638340 For the Divers Helmet I shrank down Jimsons design and glued it to the lid. Printed the little skull in glow in the dark :-) https://www.printables.com/en/model/258070-vintage-deep-sea-diver-helmet
