Parametric Paddle Holder for Kayaks/Canoos

This is a replacement part for a paddle holder I printed for a friend's kayak/canoo a while ago.

I was told it fits and works perfectly, but unfortunately I don't know the brand of the boad, or even how the paddle holder is attached to the boat. If you recognize this part, please let me know since naturally, I'm curious! :-)

Print in PETG with 100% infill for strength.
