Carbon Fibre Focuser?

[Robert72]

On one of the forums a while back someone jokingly mentioned making a CF Focuser.  Has anyone designed, or better still, fabricated such a thing?  I am currently brewing up a few ideas and wondered what might be out there.

If you have a 3d Printer you can get carbon fibre PLA now

Yes, carbon fibre inclusion has been available in various filaments for some time now.  It's very abrasive and will wear out a normal brass nozzle very quickly I gather.  To avoid this there are steel or ruby nozzles at a considerably higher cost.

Printing with CF-filament indeed wears out the nozzle, rather fast.
It has been said that for each reel of filament that has been printed with a brass nozzle it should be replaced.

Strange, I expected it to be more expensive.  That CF-PLA from the link above only cost £26.

The DIY section of the current "Sky & Telescope" includes a 3D printed carbon fibre focuser.
