Right now still WIP (right now this is the final Version but it might be okay).Previous Version failed because the connection between the Casing for the inner gear and the teeth on top was too fragile. I changed the Wall Thickness for the Teeth on top to ~2mm and added a 1mm bottom to increase surface between these two areas. Chamberlain will only sell the whole Drive Unit even though this is the only part which will fail if the Gate is opened by hand.
