Description

sorry for the german part names
klein = small
gross = large

usable with the wade extruder.

large gear:
teeth: 39
hole and hexagon made for M8 hexagon head bolt

small gear
teeth: 11
hole: 5mm (for NEMA17 engine)
axial hole 2.5mm for M3 thread. (Don't know if this works well. Haven't test it yet)

axial distance: 40mm
Still work in progress :3

Software used:
Inventor 2012 Professional
(Skeinforge44, Sprinter Firmware and Pronterface Host)

Instructions

the small gear got a 2.5mm hole so you can cut a M3 thread in it. if this dont work you can still push in a flat M3 nut in the slot.

Thats looks really nice and good resolution. What printer, extruder size and settings did you use?

WOW! Now that is Trick! Paint or foil some copper/brass on some sections and really start to Steam Punk that bot. This is pretty nice.

now i found the comment section xD

1. i don't know how to export these models as OpenSCAD format from inventor. i could provide STEP files though.

2. yes they are helical cut. i did it just for the good looking. i don't think there will be that much axial forces.

3. thanks for all the likes and comments :3 this is my first thing
i uploaded and it's still WIP. I'm about to load up other designs in the future.

Very cool. The teeth look slightly angled... like a herringbone gear?

Its a helical gear... not ideal as it introduces an axial force. Herringbone gears avoid that problem.

I really like the beauty and efficiency (in terms of amount of plastic used) of these parts. Having it available as an OpenScad thing would be like getting a giant lollypop!
