Leonardo Da Vinci was fascinated by escapement mechanisms that measure time. He studied a number of them.
Based on his work, the kit uses the laws of motion and a flying pendulum escapement to keep accurate tieme.
The pendulum's weight acts as the clock's power source.
The kit needs no glue or battery in order to assemble a fascinating, working model.
NOTE: I have not printed the entire model, only some pieces, but I have the original and the pieces are measured with calipers, so I DO NOT GUARANTEE that everything fits well, the hardest thing to find are going to be the metal bars,
NOTE 2: In case any part does not fit, let me know and I will modify it in Tinkercad and I will send it to you.
NOTE 3: Attached is also the PDF to assembly.
