OpenSCAD configurable circular bead plate

Remix of the very nice OpenSCAD file found here:

I modified the original OpenSCAD algorithm so that spike spacing works better with larger circles. I also adjusted the spike dimensions and included a wider brim around the perimeter of the base. I also increased the ring diameter increment to 5mm.

As an aside, I also will add that I recommend printing the following tweezers which I found are very useful when working with the beads. They provide a clamping force by default that can hold the beads successfully in a variety of ways. There is a single .stl file (Mini_cross_tweezers.stl) that prints all three parts at once in just a few minutes:

Have fun!
