Water Ski Wing

This is a slalom water ski wing. I copied one from an old O'brien water ski. I made the wing brackets slightly thicker. I included a sketchup 2017 model, a DXF model, and the last STL file I used. Think I had to change the holes from a circle to a square to prevent an error with the slicer I used. Then I drilled out the holes for the screw.. I think I bought #4 x 3/8" or SS pan head screws from a Hardware Store.

I wasn't sure how durable these were going to be, So I printed out 4 set of wings, then some more to demonstrate how the printer worked, and 2 years later, I am on the original wings.
