17-Year-Old’s Quirky $20K/Month Side Hustle

An interview with Michael Satterlee 👇

The business is SoleFully = 3D printed accessories for Crocs.

💬 Michael says…

I started in 2023 after learning 3D printing in my design and drawing for production (DDP) class. I decided to buy a 3D printer and started researching product ideas. 

I came across a story about someone making a lot of money selling snow plow attachments for crocs and realized there was a huge opportunity. I jumped on it and built an entire store around that niche…

TikTok and Instagram have been everything for me — that’s where all my marketing happens. I average around 50 million monthly impressions, and it’s 100% organic. I’ve never run paid ads, just consistent, creative content.

What niche or industry are you already familiar with?

Might 3D printed accessories work well there? 🤔
