Source/Remix: openscad auger library
[thanks buddy, the auger lib is an awesome lib]

Fits: 5mm stepper D-Shaft

Set for 15% overhang with no supports.

Made this thing to process large dog food. All the dog feeders out there fail when processing large dog food.. Not this..

The auger side d-shaft will snap together very tight, careful not to break the auger.

Also, the stepper motor side will be very tight, again, careful.

Used in combination with 4" PVC Reducer Mount

Update
Will be remixing with coupler married to auger.
Print at 100% for maximum strength, I broke an auger at the neck today that was printed at 20%.

Note
Long auger has not been tested yet with coupler. Long auger has upgraded coupler fitting. Fitting extends down into auger flights.
