This is my own redesign of SeeMeCNC's EZ Struder. I designed it to have a tighter filament path near the drive rollers, have an inlet guide, and to combine the three molded parts of the original into a 2 layer assembly. The design originated from the manufacturer's original STL files at github.com/seemecnc A second set of files has been uploaded that is compatible with the E3D bowden style adapters. http://e3d-online.com/E3D-v6/Spares/Bowden-Adaptor-1.75mm-Filament It's essentially the same thing minus about 1mm to fit the dimensions of that groove mount snugly.

Slice, print, profit.
