`$slop` is 0.0 now.

This is redundant with issue #102. The issue is a long task, in progress.

Makes sense. You can edit your list comment, and use the markup `[ ]` and `[x]` to get clickable/checkable checkboxes, so we can check them off as they are done....

We have a script, `scripts/func_coverage.py` that lists all public functions that have no regression tests, by file. It would be possible to make PR submissions annotate themselves with that.

Updated run of scripts/func_coverage.py: ``` NOT COVERED: quaternions.scad: 1 uncovered functions Q_is_quat common.scad: 1 uncovered functions is_finite wiring.scad: 2 uncovered functions hex_offset_ring hex_offsets hull.scad: 2 uncovered functions hull2d_path hull3d_faces screws.scad:...

Currently, in `cyl()`, if you specify `r` and one of `r1` or `r2`, then the value of `r` will be used for the more specific `r1`/`r2` that wasn't specified. ie:...

I do think we want to allow mixing `r1`/`d2` or `d1`/`r2`

I've committed a tweak to `get_radius()` to make above said checks.

I went through all the calls to it, and I'm pretty certain it'll work as expected.

I've been making nut catches each time, and not even thinking about it. This is sensible to add.
