More Robust Filament Guide Bar for Prusa I3 Metal Frame

thingiverse

I like the filament guide bar by tdiggs, but it just wasnt robust enough for me. The end supports kept snapping. So this is a more robust version of the same idea. Improvements: Larger end supports with larger diameter connectors which are less likely to snap off. The inner surfaces of the guide bar are rounded slightly to allow the filament to move through more smoothly
