A simple, geometric, arcane circle to be added to a 2D or 3D gaming table layout. I plan to print up a bunch in various colors to use in my DnD game as teleportation circles, summoning circles, protection from evil... maybe even glyphs. This was specifically designed to be printed on an FDM printer with a 0.4mm nozzle. Scaling it up should be fine but down is inadvisable.
If you need a 1 inch circle, try a Glyph Marker instead: http://www.thingiverse.com/thing:2022826
I chose to give the first print some hexagonal infill to add some complexity to the internal structure.
I do most of my work these days in Cubify Design so I put this together out of circles and triangles, using various layer depths to embellish the design while keeping it fairly simple to print cleanly.
