Tiny Flex Extruder for E3D V6

**Updated 11/15/15 - no need for a teflon tube inside the extruder**

Printing solid and flexible filaments is hard. This extruder, when properly tuned, helps solve that. Two STL's are provided, one has a holder for a 12mm inductive/capactive sensor, and one is bare. Also included are the SketchUp files, so remix away.

Required parts:
[Drive Gear 8mm OD/5mm ID 13mm length](http://www.filastruder.com/products/hobb-goblin-5mm-id-drive-gear)
Nema 17 Motor
624 Bearing
4x M3x12
1x M3x25
1x M4x10
1x Spring 7mm OD 20mm length (another change from the original source, this spring is much easier to find)
2x M3 nuts

Cut the teflon tube flush with the opening of the hotend for a tight fit.
