Build. Fix. Teach. Create with Captain Kearn.
Welcome to CaptainKearn.com — home base for my work as a content creator in the 3D printing and maker space. I create videos, livestreams, project updates, and hands-on content focused on printers, mods, repairs, firmware, experimentation, and practical problem solving.
If you love rebuilding machines, chasing better prints, learning through trial and error, and making things with purpose, you’re in the right place.
Real-world maker content with workshop grit.
I’m Captain Kearn — a longtime tech professional, maker, and creator who shares the process behind 3D printer rehab, upgrades, troubleshooting, electronics, and hands-on builds.
My goal is to help more people get into the hobby, learn faster, avoid common mistakes, and keep creating. I’m especially passionate about bringing older printers back to life and helping others see what’s possible in the maker space.
3D Printer REHAB
3D Printer REHAB is my community-driven project to rescue, rebuild, and rehome donated 3D printers so more people can learn the hobby without the huge upfront cost.
- Older and broken printers get diagnosed, repaired, tuned, and tested.
- Some are placed with learners, especially in Northeast Colorado.
- Some are sold transparently to fund parts and keep the rehab cycle going.
Rescue older 3D printers. Bring them back to life. Put them in the hands of learners.
This project is built around practical making, honest transparency, and giving more people a real path into 3D printing through rebuilt machines and shared knowledge.
