Can you post a screenshot? I don't see anything, but I don't think that player let's me find the correct location either...

Looks like a 3-d printed 40 teeth gear.

Yeah, that looks 3D-printed. I wonder though why he would 3D print a standard part that is also easily obtainable online. (Unless he had a printer already available and it was easier to print it than to buy one)

From the Register article:

"Fans of 3D printing will no doubt be pleased to note that some of the parts (notably one of the large gears) came from a printer, but only because buying missing bits online tends to take longer and cost more. A real-world version of the model was designed and built first to make sure it worked. Stud.io was then pressed into service to create rendered versions."
