- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=POLOLU-88:1` (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/POLOLU-88:1.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)

The Tamiya 70143 Universal Arm Set can be used to create crank systems, link systems, and structures for your robot or other project, as illustrated at the bottom of the instructions shown here.

This set includes four 33-hole arms with 3 mm holes spaced 5 mm apart. The arms can be cut to the desired length (each arm has regularly-spaced grooves that help to make a straight cut), and the holes can be modified to create longer slots for use in a cranking system. Four L-shaped brackets are included in the set for mounting axles or for use as structural support. Also included are twelve spacers at 5 mm, 10 mm, and 15 mm lengths, eight plastic nuts, and a metal screw and nut set.
