MPCNC-C (23.5 mm conduit) Spool Hook with Filament Guide

thingiverse

I was fed up with my spool constantly coming unraveled, so I came up with this innovative solution to hang it on some extra conduit, and then I realized that sticking with such a simple fix permanently wasn't the best idea. This design is based on the shape of the 'Flashforge finder spool holder with filament guide' by kvasbo (you can find more information about it in the 'remixed from' section). It securely grips the conduit, keeping the filament taut while printing. To make modifications easier for different size spools or conduit, I've included the SolidWorks files. I'm currently using this to hold 1.2 kg 3DMars filament spools and so far it's been working great - no dips in sight! The image above shows an earlier version of this design; the newest one features a thinner filament guide arm, which you can see in the .stl files.
