Gears for Servo's / SG90

thingiverse

A selection of gears that works seamlessly with the SG90 servo includes two of each, providing versatility and flexibility for various applications. One gear is designed specifically to attach directly to the servo, while another can be secured in place using an M2 rod or bolt. The "tighter" versions feature a smaller spline that attaches to the servo, making them ideal for use with varying print sizes. With one of each version provided, you're likely to find the perfect fit for your specific needs. While I've only printed these gears on an SLA printer, I anticipate potential difficulties when using an FFF printer due to the fine grip required for the servo attachment versions. To expand the functionality of these gears, you could consider modifying one of the other options to accommodate a horn with embedded features.
