## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=GB-3203-4103-0001:1` (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/GB-3203-4103-0001:1.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

goTUBE is a versatile solution for structure and motion assemblies! It’s well-rounded thanks to a 32mm OD and the 16mm Square Pattern on its ends. The latter provides for no-slip power transmission to mounted components. And with a multi-functional bore engineered to act as both a 14mm diameter circle and 12mm-sided square, goTUBE can seat bearings and support linear drive assemblies with lead screws.

This bundle brings new possibilities to your build by giving you 2 of each of 12 different lengths of goTUBE.
