Expandable Auger
thingiverse
Inspired by printable large auger by MTO http://www.thingiverse.com/thing:8956 This was created in Autodesk Inventor using the original idea from MTO as a starting point, I then identified and corrected errors to make this concept work effectively. I will be utilizing this design for fish food preparation, while still working on integrating a motorized component and an outlet at the end of the coil. Update 11/16/15: Files have been uploaded to support the ends of the coil. These parts are specifically designed to be used with Coil 2 only. They include End Cap, Half Coil, and Flat mount options. The Flat mount allows for secure attachment of a servo horn using glue or screws.
