Seven-pointed star pendant, printed in two pieces. Back piece has flat spot to avoid discomfort and reduce wear on clothing.

The two pieces can be glued together with epoxy, clamping the two parts with a rubber band as the epoxy sets.

The OpenSCAD file is easily modified to change the number of points, the thickness of the pendant, or the "fatness" of the star.

Use a brim to keep star point that has hole from drifting.

Increase the wall thickness to prevent the infill from mottling the surface too much.

I started with an n-point star design with an inner and outer radius in OpenSCAD, then added parameterization to make it easier to customize how "fat" the star is.

I added an arched hole (to avoid the filament drooping that can occur with a round or half-round hole) to accommodate a cord or chain.

The back piece could be identical to the front, but I chose to truncate the back to make a flat spot to avoid having a sharp point against the body.
