Description
An updated version of my compact geared extruder - which now has the option for helical gears.
(Helical gears are better at transferring torque smoothly and quietly - so I've upgraded my extruder to use them)

Very Cool... thanks for posting this!
The gear thickness cannot be increased without causing interference with the mounting screws. So moving to herringbone means you need a silly overhang.
And the axial load is much less than the bearings and washers can deal with.
Why not herringbone?
Helical gears will introduce axial loads that are not really desirable.
