[OpenSCAD] 3D Printer

I have parrots and cook with teflon cookware.  I would not worry about 
teflon failing in a 3D printer or causing fumes.  But there is a plastic 
tube in some printers that can fail if they are over heated.  The closer 
you get to the theoretical failure point, the more risk you have that 
the hot end will fail.  All metal hot ends are better for high 
temperature filaments, but some of them have trouble printing PLA.
