This was created in Autodesk Inventor. I liked the idea from MTO and saw the errors and was able to make this idea work.

I will be using this for fish food and still working on the end for a motor and the end for the outlet.

Files uploaded for the ends of the coil. (Parts designed to work with Coil 2 only)

End Cap, Half Coil, and Flat mount.

Flat mount allows a attaching a servo horn with glue or screws.
