Filament Guide and Dust Guard for TOM Top Loading

thingiverse

To adapt to top-down spooling, alter the original filament guide design by printing both halves, breaking out the semi-circle, and then gluing them together. Insert a sponge inside before threading your filament through for efficient dust and clog prevention. This solution has served well for over a year without serious clogs. Note that for Thing-O-Matic compatibility, print one version for each edge and glue them together despite the "left" and "right" reversal in the design.
