Stem rotation not working in Choc_Chicago_Steno_Thumb.scad

[julowe]

When trying to render keyID = 4 in the Choc_Chicago_Steno_Thumb.scad with stemRot = 90, using all other default parameters - I get some layers that are not rotated.

Adding the rotate transform to the line with the skin() function rotates them and the keycap renders much better.

This isn't perfect though, as the stems now do not sit inside the rectangular base created by the skin() function. But they look connected and would likely print fine (not tested yet).

See attached pull request for a quick & ugly fix.
