Slice & print at around 0.15mm layers and hexagonal infill of 20-25%
Attach heatsinks onto the stepper drivers
Attach a 4010 fan and a "fan grill 40mm" (just search for it here on thingiverse: http://www.thingiverse.com/search?q=fan+grill+40mm) with four M3x15's screwed directly into the case
The enclosure can be attached to it's surroundings by cable ties through the four rectangular holes in the bottom part
- The slot hole for the microSD might be a bit too small, but it's easy to cut away approx. 1 mm from the top part of the enclosure to make a better fit for the card.
- Also you might want to attach a piece of tape to the rear of the microSD card so it will be easier to pull out.
- Hopefully next version of the PrintrBoard will feature "push-to-eject"
