// rounding = Edge rounding radius, if any. The outermost top and bottom edges are rounded by this amount. The edges of the inner hole are also rounded. If you set `trade_size` and you want edges rounded, you must set `rounding` yourself. This parameter has no default value because the rounding depends on manufacturer and bearing size.
// anchor = Translate so anchor point is at origin (0,0,0). See [anchor](attachments.scad#subsection-anchor). Default: `CENTER`
