Probably some other things I've forgotten.
Shapeways sent me my cat object(made by shapeways based on my 3D cat model which used for my virtual item in second life).
FUN!!!
i'm exciting about possibility that virtual item designers can be realistic object designers!!!
A genuine Makerbot extruder stepper motor, genuine Makerbot pinch gears, and a machined, aluminum filament feeder from the eBay seller cre8it. As of this writing, 6 July 2014, Makerbot is still selling these motors and pinch gears. They do charge a premium for the motors -- $30 USD -- but if you want a small motor, this is the ticket.

Assembled extruder with heatsink and 24 VDC fan, top view.
Be sure to use a 40 x 40mm 24 VDC fan. MBI uses approximately a 5 CFM fan, but you can get much better, quieter fans which move more air (higher CFM). The fan shown is approximately 7 CFM. Note arrows molded into the side of the fan and orient the fan such that it blows towards the heatsink.
The M3 bolts with which the fan and heatsink are affixed are 45mm long.
