I never did print my original model! It was rejected because of the technical issue with the sides. I've redone the D37 using your updated scale factor. I think it will print quite nicely now! One other thing that might make it even better is if you made the model hollow. Those of us who would like to print on Shapeways would save considerable money on printing with a hollow model.
Shapeways prints the hollow portion with support material that can be extracted after printing or even left I think in if there's no pinhole to get it out... I don't know all the details except hollow = cheaper.
Glad to hear that your d37 needs were finally satisfied! I updated the scale factor on the font depth such that you can set the value in Customizer to be able to see the text on even really large dice. I'd love to see how the print turns out!
This is a fantastic customizable design. I made a 37-sided die with it. Only thing I could see that needs tweaked is the visibility of some of the numbers. For instance, the upper right corner of the 28 and 16 and many other objects are simply not there. (I couldn't even begin to guess what caused that!)
Anyway, great job. I'm ordering a print of my D37 model, and I'll post the results eventually!

Use the MakerBot Customize to modify number of sides, font and face depth, style and size of the font, as well as the model resolution. The OpenSCAD script uses the Golden Selection Spiral algorithm to find the positions of reasonably even distribution of faces on a sphere for most values of n. Some smaller values of n use preset face angles. Due to most distributions being non-symmetrical, numbers will generally appear off-center of the flat faces in the die.
For best results of the lower hemisphere of the die, print using a raft and supports. Finish the bottom and sides using fine grain sandpaper.
DISCLAIMER: The distribution algorithm works well for large values of n, but it's not perfect. Other variables introduced while printing or sanding pretty much guarantee that it won't result in a perfectly fair die, but it's close!
