Designer

Chri

3d model description

This is a rework of the Nema14 geared extruder,
This is an reworked design of our Nema14 geared extruder from Thingiverse (www.thingiverse.com/thing:...153356)

* All drawings reworked (removed all “reprap” sources so 100% free of other licenses)

* Gear Ratio is now 10:45 instead of 10:43 (gears are not compatible with rev 1.0)

* Idlerscrew nut is now inside the body

* Spring screws dosnt require the nutholder anymore, easier opening

* additional setscrew at the Stepperarm for future dev. (cable/fanholder)

* minor changes

All parts testprinted with a 0,4mm nozzle.


This Extruder uses the same Inserts as the Nano Extruder (except of the
bowden inset which is not available) Groovemount should work without an adapter and the brass insert for 1,75mm
Filament.

Altough the Body is capable of using 3mm filament, its only designed to
work with 1,75mm+brass insert ! (for flexible materials)

If you try it anyway with 3mm and it will run don`t hesitate to make a comment to it.

Beware , there are two versions, one with 40mm Mounting holes and one with 50mm !

Running on the right setup its possible to print with up to 400mm/s!
