A design module inside your own website

Commerce has a Website configurator view. A design module runs inside a page of your own website, in your look, for the accounts your site signs in. It shows the stocked tool that fits first, then the special made to size at the account's price at each quantity, with its drawing and STEP file, and hands it to your basket.

You choose the hosts it runs on, see today's activity and open it as any account. A describe box that sets the sizes from one sentence is off until you switch it on for an account.
