Lilly impeller remake

Thingiverse is a great place to share stuff.

I did not invent this or make the original stl file. I saw it here on Thingiverse, and grabbed it up. I know a cool design when i see one.

I did, however, modify it to my needs. I made the bottom stem a little bigger and added support for printing. Then made it a through hole for a long shaft. I added the blender file so you can change the size of the shaft. Though shaft or any size or length.

original stl file came from here by yzorg
