Materials

Peek or PTFE

Benifit of Peek

no dangerous fumes if over heated.

I have 16mm diameter PEEK rod.

Disadvantages of PTFE

dangerous fumes if over heated

I dont have any PTFE.

The Original Reprap Mendel design:-

New Idea for a PEEK version of the insulator.

Diffrence from original.

1/ The top of the insulator is D shaped. 2/ The insulator mounts through a 6mm thick D Shape hole to stop twisting. 3/ The insulator is held in place with an E clip 4/ The filament clearance hole is bigger at 4.2mm 5/ The heated barel threaded length is much shorter. 6/ The heated batrrel is 25mm long
