About this 3D model

I like direct drive extruders since they are small with less parts however I find them not to be as reliable as geared extruders; with direct drive extruders I had problems with cheap filament since the tolerances are all over the place sometimes the direct drive lacks the power to push the filament through, not a problem with the geared extruder hence when I use good reliable expensive filament I'll go with the direct drive but with cheap filament I always feed it to my geared extruder machine. Since all geared extruders seem to be large and I wanted something small I made this extruder a 1.75mm geared extruder with herringbone gears that have been reduced to 2/3 it's standard size to make it compact. Latest version uses a bracket for mounting that allows to remove the extruder easily without tools. The extruder is working fine however I am still working on it to make it better it might need some changes to please more people like the mounting bracket that might need other configurations for different machines, let me know. You can always find the latest version and some other goodies in my site here is the link to the downloads area http://infill3d.com/20-downloads Please let me know what you think, I want to end up using this extruder in a delta bot eventually.
