Parametric Easy-Print D20

Finally, a D20 you can print with good quality without support material! This fully parametric model is easily generated or changed using OpenSCAD. Parameters that can be adjusted include: Diameter Corner/edge rounding Font Depth of lettering Font size Bolding Smoothness Ordering of numbers Numbering style (Arabic numbers, Roman numerals, Braille, etc.) It's all documented in the OpenSCAD file. The STL file is generated from those initial parameters and is sized at a 6" diameter - feel free to scale it to whatever size you want. Most D20 models out there have text that's inset perpendicular to the die's faces. However, this creates unsupported overhangs which make them difficult or impossible to print without support material. Most open source CAD programs don't have the ability to bevel text without a lot of manual tweaking of edge bevel insetting. This model hacks around that by using progressively inset/outset stepping, which means its text is far easier to print by simulating a proper bevel. And because it's done fully parametrically using OpenSCAD, you can easily change the font, numbering type (Roman numerals, etc.), or other parameters without messing up your edge bevel distances and having to manually rebevel. This was designed after getting a request for a novelty 6" D20. After looking around other D20 models and realizing how difficult it would be to print them without support, this was the inevitable conclusion. Please pardon the code quality - this was whipped up in just a few hours. Update April-May 2017: By request, I'm working on other dice.
