Economic Filament Spool Rod Support

thingiverse

Hey there, I've spotted some spool holders that streamline spool movement but they're often labor-intensive and wasteful when it comes to filament. I've come up with this one that needs only 4m of filament per unit - a significant cutback. I've already printed two units and they work like a charm. The outer diameter measures 51mm, while the inner diameter is 8mm. Due to the flexible design of the spokes, you can easily insert a larger rod if needed. It holds tight on an M8 screw without any issues. Let me know how it goes for you and what changes I could make to improve it further!
