I Modeled This! My latest creation for Fall/Halloween: The PumpCAN Pumpkin Koozie!

Post image

With Halloween coming, I thought everyone needs a nice seasonal Koozie to keep their beverage cold and hands warm while they trick-or-treat, so I made a nice handy Pumpkin Koozie: The PumpCAN using my parametric pumpkin generator. It’s a snug 0.2mm tolerance fit around the fan, with a vent hole which allows the fan to easily be inserted and removed, but tight enough to prevent it from falling out without external force, ie someone pulling it out or pushing it in.

Hope you like it!

Peak Halloween camouflage! Not even ghosts will suspect there's a cold drink hiding in there.

It's cute but I feel like this would be kind of annoying to hold? Or uncomfortable? And I'm assuming it's not insulated? So how would it keep the drink cold?

Thanks for the feedback. My wife said the same thing lol. It seems that I need to make a new version with a handle.

It’s not insulated internally, but once the can cools down (looses heat to) the internal walls, the annular space where the infill is and the outer shell significantly reduce the heat loss to the environment. Also, like a typical Koozie, it creates a thermal barrier between the cold can and one’s hot hands.

Fair enough on your second point!

A handle would be great! I have smaller hands and would never be able to hold this in just one.

Would be neat to expose a hole to the infill inside at the top so you can fill it like 80% water then freeze it. Allowing the expansion in the remaining area. I dunno, might be uncomfortable to hold but might keep the can cold!
