In this video I break down how I’m using 3D printed products at craft shows as a legit side gig—because yeah, I had a giant vet bill land in my lap and I wanted a fun way to chip away at it. I walk through the “small business” side of this first: keeping your personal and business money separate, setting up a DBA-style account if it makes sense for you, and making sure you’re handling sales tax correctly. I’m not a lawyer or a CPA, so I’ll tell you exactly what I did (including calling my state) and why you should talk to a pro if you’re unsure. Then we get into the craft show nuts and bolts: taking payments (I went with Square because people want to tap/swipe and be done), what to print, and—more importantly—what not to print. I’m very blunt here: don’t grab random Creative Commons files and resell them, and don’t touch trademarked IP like Star Wars/Marvel/Nintendo. I also cover how to find shows, what questions to ask organizers, how to avoid scammers, and why you need to advocate for yourself if an event isn’t promoted or signed properly. Finally, I share my sales mindset from my old Sears days: greet people, engage them, explain what 3D printing is, and use sales data (like Square reports) to decide what to print next.
