What plastic materials can I print?

Thanks for the compliment CA but I've just ordered a sapphire pro!!!

I'll email you the stls - print the direct drive extruder on the ender that way you only have to put it together once.

You can probably design a better filament holder - but mine works and there's a little trick with the filament that prevents tangles. :-)
Anyway I'll put it in the email :-)
