Post and Hole Fit Test

I was learning OpenSCAD and wanted to know how much tolerance I'd need to build in to make models that needed to fit together with posts and holes, so I created this test.

This project uses a set of tiles to determine how much extra tolerance is needed in my OpenSCAD projects to fit circular parts together.

The tiles are split up into multiple files:
* hole_tolerance_post.stl - The base tile with a post with radius set to 4mm.
* hole_tolerance_TOL200u-to-280u - hole radii of sizes [4.20,
