Spiral array of Constant Breath Solid Rollers

Adds the ability to print arrays of rollers where the number of need not be composite, Any number of rollers may be used and keeping the packing tight should reduce print travel time. Additionally the Archimedean spiral is that the rollers print onto is interesting itself.

About Constant Breath Solids
I came across ‘Curves of Constant Breadth’ in an old book – ‘Riddles In Mathematics: a book of paradoxes’ by Eugene P. Northrop. Northrop introduces the idea of Curves of Constant Breadth by questioning whether a roller used under a sledge for moving heavy objects must be round. Surprisingly, the answer is “No.” Northrop produces the example of the Reuleaux triangle as a Curve of Constant Breadth, though he notes that the Reuleaux triangle makes a terrible roller due to its relatively sharp points. However, Northrop notes the points can be smoothed by prolonging the sides of the triangle some distance (s) and drawing a curve of radius (s) between the two extended sides. Where the b
