Description

In this episode, we are joined by Glenn Woodhouse. Brought to you by PCBWay (https://jle.vi/pcbway) and OctoEverywhere (https://octoeverywhere.com/welcome?id=podcast).


Glenn is a retired mechanical engineer and former tech manager in the electronics manufacturing and semiconductor industries. Since stepping into retirement, he’s channeled his expertise and passion into creating meaningful contributions for the global 3D printing and DIY communities. One of his standout innovations is the Filamentalist β€” a passive filament rewinder system that simplifies and enhances multi-material and multi-color printing workflows.


In this episode, Glenn shares the inspiration behind the Filamentalist project and reflects on the importance of community-driven innovation, creative problem-solving, and the joy of giving back through engineering.
