I would to learn about Gears. Build a Plate with two Pins from Pin Connectors V3 (Tony Buser), Modified by Emmett Lalish. I define the Distance between the two Pins to 50mm. Define two Gears. A Gear 1 with 10 Teeth. A Gear 2 with 6 Teeth. Calulate r1 + r2 = 50mm r1 / r2 = 10T / 6T give r1 = 31.25mm and r2 = 18.75mm Modul = 6.25 (2xr/T = 2x31.25mm/10)On Google Play i found a App with Name Zahnradberechnung. It works simple and has Gear Pictures. PS: I had Problems with the Pins. They break, when i press the Gear over the Pins :-(
