Parametric Commemorative America250 Poker Chip

A customizable poker chip for the 250th anniversary of the founding of the United States.

This is a somewhat parametric America250 (celebrating the United States' 250th year since Independence) commemorative poker chip designed for patriotic and civic organizations. Spinning Jenny is not at all about commemoratives, memorabilia, or even items requiring much artistic talent (for one thing, our CEO only sees in gray scale). But we got asked to create a poker chip for a friend, and someone saw it and asked if we could do something for their organization, so here it is.

The chip is an excerpt of a pretty robust customizable poker chip printing program that grew out of the project and that I'll publish soon.

It's parametric in the sense that, if you like the front design as is, and only want to choose between the backing rectangle design or the plain face design on the front face, whether you want stars or not, and if you have some relatively short text that you want to wrap around a logo that renders well in a 20wx9h space, then it's completely parametric. Otherwise, the code is "extensible" as they say.

You can also choose whether or not to have the contrasting edge notches, whether you want to coin reeds or smooth sides, and whether to include a keychain hole. And you can also raise the top design slightly instead of leaving it flush for a more "presentation" feel, I like the flush appearance better, but feel free to try it both ways. If you do raise it, a factor of 0.25 or 0.5 works best - more than that and the printing isn't reliable. If you want to make more changes than that, then it's not parametric. Color selection is entirely on the slicer - it renders as 5 separate STL files that you can colorize the way you want (so the white background one is from the same rendering as one of the blue background chips.) My favorite is the flush, blue background with white rectangles backing the red text - the red straight on the blue background tends to look a little washed out, and - as was pointed out to me - the white looks more like a Christmas snowflake than the 4th of July. The raised looks a little ornate but some people prefer that look.

Lot's of details on how to print with good results in the readme file.
