Oh, these are good. They nicely fit into the Mini-Tool. Thank you!

When I try to tweak them in OpenSCAD (version 2014.03), something goes wrong:
knurled = false;
results in a screw within a cube.

Any idea what I'm missing here? (being an OpenSCAD-newbie, obviously)

Thanks in advance.

I am afraid I don't know the answer to this. I don't know what version I developed under but when I tried your parameters in "2015.03-2" (the system package on debian jessie) I get a different problem that the one you describe -- ERROR: CGAL error in CGALUtils::applyBinaryOperator union: CGAL ERROR: assertion violation! Expr: itl != it->second.end() File: /usr/include/CGAL/Nef_3/SNC_external_structure.h Line: 1149 and the thread is missing altogether. :-/ Here, using shaft_ht=24 gives a good result when rendered and exported. I'm trying to attach this "long" screw to this reply, let's see if that works.

That did the job, my daughter is very happy now. Thank you.

Many thanks for this :-)
