## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA3837:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/ADA3837:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

If you bought a servo from Adafruit you probably got a bunch of plastic add-ons that you can snap onto the rotating part of the servo. These are called 'servo horns' and the standard ones you'll get are plastic pieces. They're good but often short and not very strong plastic.

This Machined Aluminum **Servo Arm** lets you bring your A-Game to servo projects. It's strong anodized aluminum. Looks great, is easy to install and will last for a long time.

The servo arm is 37mm long and the arm part is 2.5mm thick aluminum. It has four tapped 2mm screw holes. The holes are 15mm, 20mm, 25mm, and 30mm from the center rotational point.

The center part mates with 25-tooth servo axles. Adafruit have found it's compatible with Adafruit's standard-size servo motors:

- [Continuous Rotation Servo - Feetech FS5103R](https://core-electronics.com.au/continuous-rotation-servo-futaba-s148.html)
- [Standard Servo - TowerPro SG-5010](https://core-electronics.com.au/standard-servo-towerpro-sg-5010-5010.html)
- [Standard Size - High Torque - Metal Gear Servo](https://core-electronics.com.au/standard-size-high-torque-metal-gear-servo.html)

But it **will not fit** neither the Parallax Feedback 360 Degree High-Speed Continuous Rotation Servo nor micro and sub-micro servos.
