Summary

Fear of loading the last of a spool of filament for it to run out while you're not around? Fear no More!

Confounded by a "runout sensor" mounted miles from the actual extruder, unable to detect a filament break? Be confounded no longer!

Tired of trying to load filament into a poorly designed sensor that assumes all filament is perfectly straight and all hands are elfin? Tire no longer!

Frustrated with models where no consideration was given to actually printing them? Be frustrated no longer!

Not wanting to pony up the towering wads of cash required for a prefab runout sensor? This simple sprite extruder mount requires only a $0.40 microswitch, a 10T85 with roller attachment.

Quick and simple to print, thoroughly tested, easy to actually load with filament! Whisk your cares away and print free of hassle!
