Assembled extruder with heatsink and 24 VDC fan, front 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.
Top view of the heater block mounted to the heat spreader bar and XY plate. The top of the thermal barrier tube should not project above the M6 hex nut. Try to keep the sides of the M6 nut parallel to the long edge of the heat spreader bar. This helps prevent interference with the face of the extruder stepper motor.

Probably some other things I've forgotten.
This is just one style of mounting the Y axis endstop. If you instead use

you may find yourself doing something different. Or if your mount can clear the Y rod mounts, then you may be able to engage the upper portion of the X axis rod holders which ride on the Y rods.
We got a 3D printer at work.
We're still trying out how it works best
This is the first object with 1/8 mm resolution, an owl made of ABS on a Lego brick from Thingyverse.

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!!!
