Knowing you Jeremy you’ve probably got a home brew laser cutter, and a little foundry in one of your outbuildings. I’m sure you could knock some out for us at a reasonable price?
Very likely! However, I bet there's some bloke in China already preparing production ... and he'll likely get them to the UK cheaper than we could make them! They do look like a spectacularly simple design ... come on manufacturers, get cracking, you're sure to beat the current price.
