In August 2025, one Instagram post about a double can cooler brought Mike Satterlee hundreds of orders in a single day. He sat down to work out how long his 60 printers would need to clear the queue. The answer was about six weeks.
Most print business stories stop at the viral moment. This one is more useful because of what came after it. CruiseCup went on to gross $808,000 in 2025 across its website and TikTok Shop, a figure CNBC checked against documents. The same report says Satterlee, now 19, pays himself $500 to $1,500 a month. Both numbers are true at once, and the gap between them is the real story.
From Crocs charms to car accessories
Satterlee learned 3D printing in a high school class and bought a printer for about $500 in September 2022. In June 2023 he started Solefully, which made shoe charms for Crocs, from his parents' basement. By his own estimate it took in roughly $250,000 in 2024, enough to rent a $3,600 a month warehouse that November.
Before finishing school he began trying new products. Universal car cupholder adapters drew more attention online and earned better margins than the charms, so he closed Solefully in June 2025. He told Entrepreneur he also had spare printers and wanted a new store to put them to work. An existing machine is a cheap test lab, and he used his that way.
The product that took off
The hit came from fixing a small annoyance. Satterlee opened the top and bottom of a hard can cooler and added a raised cap, so a fresh can pushes the empty one out, much like reloading a shell. He says the first prototype worked within a day, and he credits his CAD experience.
CNBC calls it the tactical reloader. In Entrepreneur it is the Beerzooka. Either way it is his own design, and CNBC says documents show two patents pending on CruiseCup products. He did not buy a popular file and hope.
The numbers, month by month
Satterlee gave these figures in a first-person account for Entrepreneur. They are his own and unaudited.
| Month | Sales | What happened |
|---|---|---|
| August 2025 | About $100,000 | Viral post, no Facebook ads yet |
| September 2025 | About $55,000 | Paid ads begin, organic views weaken |
| October 2025 | About $100,000 | Ad spending increases |
| November 2025 | About $315,000 | Best month |
| December 2025 | Not given | Ads stopped to fill holiday orders |
| January 2026, to date | About $25,000 | Ads off, poor ad costs, slow winter demand |
Look at the spread. The best month was more than 12 times the January figure so far. Multiply November by 12 and you get about $3.8 million, which is the kind of headline this business could have claimed. The documented figure for the year was $808,000, and that is the one to trust.
He also says one video reached 50 million views without paid ads. That is reach you cannot schedule.
What went wrong
Capacity was the main problem. Satterlee says three cups fit on a plate and take about 15 hours, and that about 150 printers top out near 400 cups a day. That works out to about 2.7 cups per printer per day, or roughly 13 hours of printing out of 24. A printer running all 24 hours could do almost twice that. The gap covers plate changes, failures, repairs and anything else the machines are doing. Plan with a figure like this, not the slicer's estimate.
Printers cost little, he says, with most being Bambu Lab A1 machines under $300. Yet during the August rush he waited until revenue built up before buying more. Being self-funded means no debt, but customers wait while the cash arrives. The fleet has since grown to 160 printers.
He also describes breakdowns causing backlogs during viral spikes, trouble hiring affordable staff over the holidays, and Facebook ad costs that got too high in January. Those problems all arrive when sales are strongest, or just after.
Then there is pay. CNBC says the company is profitable, but Satterlee would not share annual profit. The rest goes back into printers, ads and products. His low salary works because he lives rent-free with his parents. A seller with a mortgage would have a very different business at the same revenue.
One caution on the details. In January, Entrepreneur described a 1,500 square foot warehouse, two full-time staff and an August 2025 launch. In October, CNBC described 3,000 square feet, one other employee and a CruiseCup that had already overtaken Solefully by June 2025. Time may explain some of that, but treat these operating details as approximate.
Moving past printing
The most telling part of the story is where it is heading. In January, Satterlee said he wanted the product made in metal, with about 10,000 units ordered up front, so ads would no longer be limited by production. By October, CNBC reported him sourcing stainless steel models from a Chinese manufacturer alongside plastic printed in New York.
So printing did not scale this product forever. It proved the demand cheaply, then helped justify a bigger order. He says as much: if something sells printed, it can sell manufactured.
Three lessons to copy
Going viral is not a plan, but the method behind it can be copied. For a related product line, cup holder inserts and console trays sell at $25 to $60, with medium competition.
- Test on free video before you pay for ads. Satterlee tries ideas on TikTok and Instagram first, and estimates about 90% of what works there also works on Facebook ads. Run the same test with your own products, using real orders as the signal.
- Know your real daily output before a spike. Count units per printer per day, including failures and plate changes. Then decide what queue you will accept, and when you will pause sales.
- Budget from what you keep, not from gross sales. Put the numbers into a calculator, expect sales to fall when ads stop, and remember that $808,000 in sales can still mean a $500 month.
