Mine is a remix of this. Also, thanks to some of the propeller people, and

and reinforced shaft

this is still a work in progress, but this saves print time

I redesigned the handle/shaft, I cropped it to use just the top, and removed the handle part.
I REPLACED the handle with 3 / 4 inch PVC, 3 1 / 2 inches long, and took dremel drill and cut out space to access the rubber band, and left it intact at the top.

I created a CONNECTING WASHER, flat part gets glued to the top of the prior handle, and bottom part centers on the PVC, again using glue

I USED GORILLA GLUE, see picture

I then used 3 / 8 inch PEX (could use PVC also, even 1 / 2 inch PVC), 3 1/2 inches long, for the pull handle, to attach string.

See photo, see all parts.

Then see it assembled, top part,
