I hate waiting for the posty...

I've considered making a plastic extruder for my CNC router as it wouldn't be hard to design it to fit in the existing 80mm spindle mount, making it a quick change between router and rapid prototyper. However I'm not sure what I'd actually make with it (which doesn't normally stop me!) since the finish on the 'hobby' ones I've seen is still quite rough compared to the commercial printers. If you can make something as good as the commercial ones then there's a lot of money to be made from rapid prototyping for companies. I recently saw some parts that the company I'm at got rapid prototyped from nylon. I could cut them on my router for less than they were charged.

I thought he meant he had some alu profile and some rails lying around that he was going to use. Made sense to me.

I know what it actually meant...
