This is a cup holder that holds on to a kayak or stand up paddleboard (SUP) via the bungies cords.
My sister found this product on amazon for ~$20, I told her I could probably print one. Found an STL file online that someone was selling the design for $4. I thought about it, and decided that it is basically just a tube, I'll make my own and post it for free.
Designed in Tinkercad with generic 12oz can dimensions, used a stretched out "S" to cut the slit for the bungie. Added the text and image. Originally thought to make these an indent, but I think this adds better grip. Paint would also make it stand out really well.
Original printed version was 15mm taller than the version I uploaded- It was a bit harder to remove the can from the holder. First version seen in pictures. New version not yet printed.
