Spur Differential. Take a close look at this functional sample of spur differential, designed specifically for students or anyone who wants to see how it's made and works. You can even help me make more creations like this one. Find my designs on pinshape: http://pinshape.com/users/27920-jsirgado - Here you'll find the OpenSCAD file, which you can modify as needed. Follow these steps: 1. For 12-teeth gears, use six allen screws with a diameter of 3mm and a height of 35mm. 2. For the central axis, two allen screws with a diameter of 4mm and a minimum height of 40mm are required. 3. Oneallen screw with a diameter of 4mm and a height of 35mm is needed for the handle. 4. Lastly, a single 4mm diameter and 20mm tall allen screw is necessary for the grip. 5. Additional parts such as nuts and washers are also necessary. Using more washers can help align the gears and reduce friction. Two nuts together will be required to keep the frame and gears in place. 6. Don't forget: you'll need two central axes, each aligned but separate. 7. One screw per 24-teeth gear will complete your spur differential.
