About this 3D model

9/3/2016: Updated shaft hole size. This version should fit much better. And if you still have fit problems, I've uploaded the .step file for easy editing with your CAD program of choice. (For real people, stop uploading just the stl file. CAD files (.step or .iges) are desperately needed in the 3D printing community for the purposes of easy editing! Seriously, let's put a stop to this nonsense. Upload your CAD files. We all know they exist. People need them!) Easily slip this feed wheel onto your Printrbot feed motor shaft. Allows you to manually feed filament into the extruder by turning the wheel. Now you don't have to channel your inner Hulk and simultaneously mash down on the feed lever while using the other hand to feed the filament. Also provides a better visualization of the feed motor during printing. Plus, now your printer looks mesmerizing while it's printing! Comes with the Printrbot logo imprinted (no association with Printrbot other than the fact that it was designed to work with it).
