FunWater Paddle Clamp Clip
thingiverse
The FunWater (some at least) have a pressure lock to allow quick adjustment of the paddle length. This lever lock clip on mine came off (the retaining pin is not well held). So, I created this piece to replace it and used a piece of an old wire hanger as the hinge pin. Worked like a charm. I'm including a link to the onshape original part in case you want a different hole size (suggest 2-2.5mm). Note that this part has a proper orientation. It should be printed on it's side with support material. You want the layer direction to be perpendicular to the lever pin for maximum strength.
