Battat Plane Propeller Mount

This is a replacement propeller mount for a battat toys plane. We lost ours, and this piece is needed to attach the propeller, so I designed a new one.
I made a few versions, one that's closest to the original but needs supports, one easy to print on the front but missing the screw stop nub, and one easiest to print from back but missing the long screw sleeve.
I recommend the last one, since its easy to print and the screw sleeve is non essential.
I also uploaded my solidworks part so you can customize if you want.
