Similar to my other design. I really wanted to get rid of the overlapping sections so there would be a clear grove on spiral pattern. I edited the other design in Blender and directly changed the mesh, removing and adding faces to get the final result.

I'd recommend printing at about .25-.3 layer height at most, concentric layers, lower range of temps, and lower speed to reduce the stringiness cause if it's stringy then you have to removed the strings in the holes. I tried using a lighter to remove the strings, but beware that it can burn the print color. I used PLA because it doesn't really require extra strength and shouldn't experience high temps.

I would actually like to see it printed at an even higher resolution, but with my printer set up I don't believe I can achieve that. (Well I haven't even tried though...)
