Ep. 67: Glenn Woodhouse on Solving MMU Filament Management through the Filamentalist

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 — 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.🎁 Get $5 off your first order at PCBWay: https://jle.vi/pcbway 🎁 Get 3 Months of FREE Premium Perks at OctoEverywhere: https://octoeverywhere.com/welcome?id=podcast 🤫 Get behind the scenes and exclusive content on my Patreon: https://patreon.com/thenextlayer💬 JOIN MY DISCORD: https://jle.vi/tnl-discord🎥 IN THIS EPISODE: 🎥00:00 Introduction01:06 Meet Glenn of The Filamentalist Project02:04 Glenn's Journey in Engineering and 3D Printing05:58 The Birth of the Filamentalist Project12:28 Technical Deep Dive: Filament Rewinder Mechanics21:38 Collaborative Development and Community Feedback28:06 Polycarbonate Enclosure Challenges31:15 High-Speed Printing Insights32:59 Blob Purging Technique35:58 CAD Design Tips for Hobbyists43:01 Current and Future Projects49:19 The Spirit of Open Source 3D Printing51:19 Conclusion🔗 CONNECT WITH GLENN: 🔗 👉 Filamentalist Project on Github: https://github.com/Enraged-Rabbit-Community/ERCF_v2/tree/master/Recommended_Options/Filamentalist_Rewinder👉 ERCF V2 Server on Discord (scroll down for the Filamentalist user help/sharing channels): https://discord.gg/hxe9eMWseT🛒 RECOMMENDED GEAR: 🛒📍 Complete list of 3D Printing accessories: https://kit.co/jlevi/3d-printing📍 Complete list of my videography gear: https://kit.co/jlevi/content-creation📍My favorite thing to 3D Print: https://jle.vi/multiboard📍My recommended electronics & control boards: https://jle.vi/bigtreetech📍 My favorite 3D printing "accessory": https://jle.vi/magigoo | https://jle.vi/whambam📍 My favorite 3D printing filament: https://jle.vi/polymaker📍 Check out the official TNL merch: https://shop.thenextlayer.com/📍 PLEASE CONSIDER SUPPORTING THE CHANNEL BY SHOPPING USING MY LINKS!
