Impressive, can I ask what machine they are printed with & what type of filament used. How high a print resolution is required to get the gears to
be strong enough to use?
I no longer run Furore Products or Furore Cars Ltd, but would still highly recommend them for Acewell dashes, projector headlights, dominator
headlights, indicators, mirrors etc, best prices in the UK! Take a look at http://www.furoreproducts.co.uk/ or find more parts on Ebay, user names
furoreltd & furoreproducts, discounts available for LCB users.
Don't forget Stainless Steel Braided brake hoses, made to your exact requirements in any of around 16 colours.

I suppose the resolution only needs to be good around the teath and the shaft hole. First time I've seen plastic parts strong enough for this
tbh, though I have heard of working guns been printed off so they must be quite strong. cool

Hey guys, material is abs plastic.
Resolution in the X-Y plane is around 0.02mm so good enough for the teeth.
In the Z plane I used a layer height of 0.35mm and a fill ratio of 20%
These teeth are for a 1.25mm pitch thread so the gears are 40 Tooth, 127/100 Tooth for the idler and the final one is 80 tooth.
The large one took almost 6 hours to print. The smaller ones less.
Re price, the spool costs around 40 per KG so re cost I'm guessing a few quid in materials? Didn't factor my time as its more of a
hobby.
This is my machine

The file for 3d printing is an stl file. I used google sketchup to draw the gears.
