Design Goals
Develop a cup that can keep lattes cold without the need for ice.
Core Processes + Tools
3D Printing, CAD - Fusion 360, CAM, Design for Manufacturing
Materials
Clear acrylic, 316 stainless steel, O-rings
Inspiration
I notoriously drink my lattes slowly, so by the time I get halfway through the drink, the ice has melted and the coffee is diluted.
Typically, I use a Hydroflask with its strong vacuum insulation, but the wide mouth wasn't designed for coffee.
Starbucks acrylic cold cups are designed for iced coffee, and utilize air as insulation with a double-walled design. Though they'll maintain drink temperature, they (like Hydroflasks) aren't designed to cool the coffee down.
