Battat Plane Propeller Mount (with alignment tab)

We were about to put our Battat plane out for the next garage sale, but were missing the propeller mount.  I started to design my own replacement (including the anti-rotation tab included here) but it fell by the wayside for about a year.  Coming back to it, I discovered legosrock's version, was about to print that when my better half found the missing piece!

There's an alignment tab that prevents the propeller mount from rotating when the propeller bolt is tightened.  I added that feature to each of legosrock's versions, have uploaded those here.

See the original for printing recommendations - having found the original part, I haven't printed the parts myself.

Added an alignment tab to the original to prevent part rotation when the propeller bolt is tightened.
