OpenBuilds Extruder

2016.02.06: Added the short_inductive version. This is designed to fit a 4mm inductive probe close, but not dangerously so, near the extruder. Be sure that you don't run your extruder wires near the sensor or you'll get some consistency issues.
2016.01.14: Uploaded the short version. Same extruder, same gears but I have reduced the filament path as much as possible so when the filament leaves the hobbed bolt, it travels 23mm before it hits your extruder. Any shorter and I'll have to redesign the guideler.
2016.01.13: Updated the latest version. I had uploaded the wrong rev which had the filament slot too small and not enough room for the guidler bearing. Sorry about that.

NOTE: Filament tolerances are TIGHT on this extruder. If you are using cheap 1.75mm filament that is out of spec it might jam up. The tradeoff though is that flexible filament is a breeze.

This is a geared wades extruder for 1.75mm filament that is designed to bolt directly to a piece of openbuilds 20mm v
