Cup Holder for a Stand Up Paddle Board (SUP)

This cup holder is designed to be put on a stand up paddleboard to hold a drink. The slot in the cupholder is for the elastic strap on the SUP to slide into and this is what holds it onto the board. This is sized for a Double wall stainless koozie (hydroflask and ello are confirmed to fit well).

To help with retention you can leave in the sun for a bit and then squeeze the top together, when it cools this will help pinch the can/koozie so that it is less likely to fall out when the board rocks.

Since this will be in the heat I would recommend a stable material, but printed in PLA mine survived 10+ days of paddle boarding in 110+ Fahrenheit heat. It did not survive being left in a black car for a weekend in that same 110+ heat.
