Planetary gear calling card (MakerBot Printable Version)

I tried to use sketchup to convert the Planetary Gear Calling Card into .stl files and failed. My better angels lost the battle for sanity and humility and I did a traceout of it with Blender.

Because y'know, ~I~will~not~be~stopped~by~mere~tools~ and all that mad scientist rant stuff.


I am a bit concerned about kerf, in that the MakerBot *doesn't have it* and as such all the gears might be slightly too large. If that happens one *might* be able to get away with just shrinking the planets.

Here's the specs I fed the gear script, fyi:
Planets:
Teeth: 14
Radius: 7
Addendum: 1.0
Dedendum: 1.2
Pressure angle 30
Tooth width: 1.5

Sun:
Teeth: 17
Radius: 8.5
Addendum: 1.0
Dedendum: 1.2
Pressure angle 30
Tooth width: 1.5

Ring:
Teeth: 45
Radius: -22.5
Addendum: 1.0
Dedendum: 1.2
Pressure angle 30
Tooth width: 1.5
