Bathtub boat with wind up propeller

really good print! works really well!

I made it in PETG, is a nice and simple print but doesn't work for me, I try with different rubber bands with bad results in the propeller functionality...

Pretty good. I do not have the perfect types of rubber bands but what I have works too.

Fun little print. I’m going to play with rubber band sizes and prop sizes to see how far I can get it to go.
Thanks:)
