A bushing for the Solidoodle that helps align the filament to prevent bunching. Inspried by zimmer62's design.The filament kept pulling off the spool on bigger prints. With more length the plastic draws vertically first. This print also has a small 20.2mm notch to help hold it in place. It needed a good couple of pushes to secure itself. The notch could probably be reduced down another .1mm for a better fit.This thing was made with Tinkercad. Edit it online https://tinkercad.com/things/4DMqUIm1vwQ
