Extruder Design

After successful lashups, I've completed design for a "prototype" version. I have the materials, just need to construct.

In addition to minor fixes from the lashup, the main difference is use of an aluminum housing instead of the cement board. The hope is that the housing will dissipate the heat by operating as a large heatsink.

This extruder design aims to work towards eliminating the PTFE part. This version still uses the PTFE, but not as a structural element. Later, I hope to cool the inlet and avoid the PTFE.
