Herringbone Gear set for Huxley Extruders #30DoC Day 2

Day 2 of 30 days of creativity month brings an update for my eMaker Huxley printer, it's only ever had normal gears, and I have been using Herringbone gears on all my other extruder's.

The Huxley extruder uses a Nema14 motor and smaller gear spacing than a normal Wade/Greg Extruder.
It's also using an M6 hobbed bolt.

I have used the same great SCAD script from Triffid Hunter to make a drop-in replacement for Huxley sized extruder's.

I didn't have a lot of time to optimise the hole spacing perfectly, so it is a little tricky to fit, but well worth the effort. Take your time and get the motor aligned first, fix the motor tightly, then tighten the hobbed bolt onto the large gear, fit washers and bearing and slide both the large motor into the body and at the same time the smaller gear onto the motor shaft, tighten up the smaller gear to the motor shaft.

They print very well with a 0.5mm or smaller nozzle, use one outline and >30% infill.

All the files are up on Thingiverse here

Enjoy perfect printing with Huxley.

More tomorrow.
