How it works

- Slide the base under the bungee cords on your paddle board or kayak. - Twist the cup onto the base . The bungees drop into the channels in the base, and the twist-lock traps them, so the SUP CUP can't lift off - even upside down. - Drop in your drink . Use an insert if your can or bottle is narrower than the cup. - Optional: clip on the phone mount and hold your phone and shades in place with a hair elastic

Feature overview

Insert System

- Inserts reduce the opening so narrow drinks don't tip inside the cup. - The “Main insert” snaps into the SUP CUP, and the Can/Bottle inserts screw into the main insert. - Store your inserts inside the phone holder for easy transportation Insert Holds Opening

Main Insert Smaller tumblers and coozies   ~80 mm

Can Insert Standard 12 oz / 355 ml cans, 16 oz tallboys, 50 cl EU cans, and slim cans ~66 mm

📝 Note: The images and videos do not show the new screw-on insert style - I made this improvement after recording and editing.

Add-on: CryoPod Freezable Can Holder🧊

The CryoPod Insulated Can Holder is a freezable, parametric, can holder that doesn't just insulate your drink, it actively cools it 🧊.

After posting my previous SUP CUP design, I received many requests to create an insulated or freezable version of the insert system. There were already several great insulated can holder designs on Makerworld, so I decided that it would be better to partner with another designer in the community to integrate with their design, rather than reinventing the wheel. I reached out to Michele , the designer of the CryoPod Insulated Can Holder, and they were more than willing to team up.

CryoPod Instructions

- Print the “Classic” or “Duo” SUP CUP profile - Head over to the CryoPod page and print their “Classic Pod” profile. - Follow their instructions to properly freeze your CryoPod, then drop it in the SUP CUP and enjoy! 💬 Comment on this model if you'd like me to make any custom SUP CUP sizes that fit Michele's other CryoPod options (sleek, slim, etc.).

Add-on: Magnetic Base 🆕🧲

This base replaces the twist-lock with magnets. I removed the slots from the magnetic base so you can optionally add double-sided adhesive and make it a permenant mount.

- Print the Classic or Duo print profile (optionally, remove the original base if you dont want it) - Print the magnetic base print profile - Purchase the 10x3 magnets linked in the Parts section of this page (8 magnets needed total, 1x 20 pack will do) - See the attached Assembly Instructions for guidance on installing the magnets
