Customized version of http://www.thingiverse.com/thing:2094215

Created with Customizer! http://www.thingiverse.com/apps/customizer/run?thing_id=2094215

EDIT: Once I made one correctly and got the light placement figured out, it was easy to see that this actually worked! even at a scaled down version.

FYI: This is a negative and smaller version of

Threonin- To say this is pretty awesome is an understatement. Nice work!
I made a custom one and it didn't turn out as I wanted. So, I am currently printing your Einstein very slowly and at 0.2mm layer height and the max scale that will fit on the bed (90%)
I have a couple of debugging and set-up questions:
The customizer has an invert image button. I used it. (I'm used to inverting images when making lithophanes)
1) Am I supposed to invert the image if I want it to come out normal? As I decipher my projection, it makes me think "No"
2) Where is the light source supposed to be? at the center of the sphere, correct?
3) are you using a deposition type printer or a fancy-shmancy SLA printer? Looking at the holes at the top of the sphere, makes me think that you have an SLA printer.
You probably already answered these questions somewhere. Just point me at that and I will read up myself.
Dankeschön. -Joe
