The PrusaPrinter Forum has a post on creating a time lapse video of your 3D print. It utilizes an Adafruit Feather board (32u4 Bluefruit LE). The board emulates a Bluetooth keyboard and works like a selfie-stick. That’s what the article says. The only thing I would use a selfie stick for is to whack people who take selfies.
So this project is a combination of electronics, 3D printing and photography. It uses products from Adafruit and Prusa3D. I have had good experiences with both of these companies.
