How a Retired Veteran Built a 3D Printing Side Business

Can a 3D printing hobby become a real business?

In this STLFLIX Seller Story, we talk with a 3D print vendor from San Antonio, Texas, who started with an Ender 3 as a hobby and later turned 3D printing into a serious weekend business.

He shares what it is really like to sell 3D printed products at vendor events, malls, local markets, and community pages — including what products sell best, why useful prints matter, and how a commercial license can make selling much easier.

In this interview, you’ll hear how he uses STLFLIX models to build a booth full of different products, test seasonal items, sell popular prints like dinosaur skeletons and dice towers, and keep his inventory fresh with weekly releases.

🎯 What you’ll learn in this video: • How he started selling 3D prints • Why useful 3D prints can sell better than random decorations • What types of 3D printed products perform well at vendor events • Why commercial licensing matters when selling 3D prints • How STLFLIX helps vendors find ready-to-print models • Why seasonal drops can help with sales • How vendor events compare to online selling • What he would tell someone thinking about starting a 3D printing business

He also talks about the importance of choosing the right products for the right event. For example, Christmas events, Halloween events, kids’ events, gaming products, fidgets, gadgets, fashion items, lighting, and useful everyday prints can all perform differently depending on the audience.

One of the biggest advantages he mentions is confidence: having access to tested models, organized collections, ready-to-print files, and a commercial license so he can focus more on selling and less on worrying about copyright issues or whether the design will print correctly.

💡 Whether you are just starting with 3D printing, trying to sell your first prints, or building a 3D printing side hustle, this interview gives a real look at what can work in the market.
