We still haven't gotten around to actually using their services, but Minneapolis-based rapid molding company Protomold has got the Coolest Promotional Shwag prize all wrapped up. First, they sent us the infamous purple cube, making sink marks, pass-core features and screw boss design a cinch to explain. Arriving in the mail last week, though, was something that tops even that: the Demo Mold. It's essentially a super-simplified injection molding tool, complete with runner, ejector pins, slide action, and enough annotation to make the exhaustive process of describing the problem with undercuts to your client/manager a thing of the past.

On top of all that, it's a nice thought-provoker: when tooling time and cost drops to the point where you can manufacture an object to do your explaining for you, what's next?
