Anycubic i3 Mega Flex Extruders

Designed an ultra high tolerance extruder for flexible materials and to work with my direct drive mount system.

Compared to previous extruders I have downloaded and tested:

The spacing between the drive gear and guide wheel is extremely small.
The thicker arm height increases spring tension slightly.
The filament hole is precisely aligned with the travel path.

I have provided 2 variants on the design.

The "For Tube Connector" has a 6mm hole to thread a PTFE locking connector into. For use with bowden setups, or V1 of my direct drive bracket.

The "PTFE Lined No Connector" version has a 2mm hole for 15mm of PTF tube. This lines the majority of the inside of the extruder with low friction material. I recommend using this version with my V2 direct drive mount.
