CruiseCup: 19-year-old's 3D-printed can coolers hit $808K

CruiseCup founder Mike Satterlee was still a teenager in his parents' basement when he started experimenting with 3D printing. Four years later, the 19-year-old's can cooler business brought in $808,000 in gross revenue in 2025, according to documents reviewed by CNBC Make It — proof that a single cheap machine can grow into a serious company. The 19-year-old runs CruiseCup from Clifton Park, New York, selling 3D-printed and stainless steel can coolers that reload from the top or the bottom. The hard-shell insulated drink holders are sold through the company's website and TikTok Shop, with a smaller share of sales coming from Amazon. The coolers are marketed as a tougher, reusable alternative to disposable foam sleeves, and the top-or-bottom reloading design became a signature feature. The story began in a high school classroom. As a freshman, Satterlee learned to operate a 3D printer in a class called design and drawing for production, and in September 2022 he bought his first machine for about $500. He spent months learning the craft, printing small objects and selling them wherever he could find buyers. What followed was a run of trial and error familiar to any young founder. ## How CruiseCup took off The breakthrough came in August 2025. Satterlee posted about a new product, a "tactical reloader" that could hold two 12-ounce cans at once, and the Instagram post went viral. Orders poured in by the hundreds in a single day, and the company did $100,000 in sales that month — roughly 60 percent more than Satterlee had ever made in a month. The viral moment turned CruiseCup into a full-time operation almost overnight. Fulfilling the surge was its own challenge. With 60 printers running in a 3,000-square-foot warehouse, Satterlee calculated it would take about six weeks to work through the backlog. Unlike many viral businesses, CruiseCup held its momentum: the company closed 2025 with $808,000 in gross revenue across its website and TikTok Shop. ## The road to CruiseCup ran through Crocs charms CruiseCup was not the first attempt. In June 2023 Satterlee launched Solefully, selling decorative charms for Crocs shoes, which brought in roughly $250,000 in 2024 sales — enough to rent a $3,600-a-month warehouse that November. When can cooler adapters began outperforming shoe charms online, he shut Solefully down in June 2025 and went all in on drinkware. The business has been entirely self-funded from revenue, Satterlee said in an earlier first-person account. The company is profitable, though he declined to share specific profit figures, and he pays himself just $500 to $1,500 a month — possible, he notes, because he still lives with his parents and pays no rent. The rest typically goes towards more 3D printers, social media advertising and developing new products, he says. ## What CruiseCup says about 3D printing The wider market is moving in the same direction. Shopify says sales of 3D-printed products on its platform rose 112 percent between October 2025 and September 2026, as cheap machines put small-scale manufacturing within reach of hobbyists. Few founders combine Satterlee's youth with his ability to scale quickly, but the falling cost of entry means more will try. The economics favour small operators: a single printer costs a few hundred dollars, and designs can be iterated overnight. Industry watchers caution that printing is the easy part; finding a product people will actually buy is where most would-be makers fail. For Mike Satterlee, the next steps are UV printing, a broader drinkware range and, he hopes, a place on retail shelves. He now runs CruiseCup full time with a single employee, reinvesting nearly everything the can coolers earn into more printers, advertising and product development.
