Precision Rolling Pin Ring / Spacer

Precision rolling pins have auxiliary rings or spacers that enable the production of a consistent and specified thickness of dough that is rolled-out. We had one made out of wood that broke and no longer stays on the rolling pin. This replacement is just a cylindrical annulus with some filleting or rounding. The example given has a 1.5 inch internal diameter and yields 0.5 inch thick dough. A cadquery python file is included so you can make any size (or make other modifications) that you wish. So far, I've printed them in TPU (even though the originals were in wood, a hard material more like PLA etc.). The TPU stays on the roller better and provides some squish so that it can fit on slightly different-sized rollers.
