Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:667301.

UPDATE: base4_fixed.STL includes extra material around the threaded region for the PTC fitting.

Modified from Singh336's exemplary work, this remix:

• Further encloses the filament
• Reduces clearances around the idler bearing
• Increases the force imparted by the spring on the idler lever
• Realigns the idler lever for better contact with the filament
• Adds a feature that can be tapped for a stock PTC fitting (M5x0.8)
• Raises the filament entry above the idler lever for easier loading

Also included is a flimsy adapter to allow the new cold end to be mounted in the stock position on an unmodified RoStock MAX V2 or on alextoff's slick Dual EZStruder Mount as shown in the photo.
