Step 4: Use blender - check size and clean up
The process of taking a part from a design to a print are here: http://wiki.makerbot.com/how-to-print As far as I can tell, this is the best place to start.
What I have here are pretty much notes to myself.
Next I opened the STL in Blender.
I've had some trouble telling what scale I am in using openSCAD. So I imported the STL we just generated along with an STL of a know size. I used a 3cm snowflake from thingiverse(attribution).
My first scale was way, way off. The finger was so big blender seemed to be having trouble displaying it.
Luckily in openSCAD rescalling is easy. [descripion ]
Next - Makerbot recomends deleting multiple vertices
Tab-> A-> mesh ->delete multiple vertices [check]
Now we can export another cleaned up version of the STL.
