Lego Helical Gears 45 degrees 20t + 12t

Consider to follow if you like what I do. Helical gears for Lego. These are 45 degress. Resin printers are better than FDM to make the gears smooth. FDM will work but you have to do the instruction below Note this if you are using a FDM printer: You have to wear down the gears a bit before use in a vehicle/creation. Build something like in the picture connect a motor to the smallest gear and let it run for 10 minutes. After that. Connect the motor to the bigger gear and let it run for some time until its smooth. Print with 0.1 or lower. I printed the 20t gear with 0.1 and 40% infill. 12t is printed with 0.05 layerH and 100% infill. The gears gets really smooth if printed with 0.25 nozzle or smaller, but it will slide on the axle. If you want other gears straight cut or helical. Send me a message and we'll make it happen.
