An opening version of the Book of the Dead key from the movie The Mummy (1999)
The mechanism requires eight nails with heads cleaned (for example, with a Dremmel). The nails are 25 mm in size and 1.6 mm in diameter.
PETG at 15% infill.
I printed the top of the key at an angle of approximately 45-50 degrees.
You may also need to clean the grooves where the nail pin will slide. To ensure proper operation, I lubricated the lid with silicone grease.
