The round 12-sided die
======================

A friend of mine, member of my D&D group, asked me, as soon as he
discovered that I would get a 3-D printer: «can you print me the
intersection of three cylinders?»

New, the resulting object is not exactly easy to visualize, but it's a
12-sided solid, where each side would be a square, were it flat; in
fact, the sides are curved.

Obviously there is no way to print an object similar to a sphere on
the CupCake: we would need some support material. What we can do,
instead, is to print a half-sphere; we print it twice, we glue the
halves together, and we get a sphere.

Half of the die, seen from an edge

[% WRAPPER 'figure.tt' pic='img_0981' alt="half-die, from above" %]
Half of the die, seen from above
[% END %]

[% WRAPPER 'figure.tt' pic='img_0982' alt="half-die, from the side" %]
Half of the die, seen from the side
[% END %]

[% WRAPPER 'figure.tt' pic='img_0983' alt="half-die, from the side and
edge" %]
Half of the die, seen from the side, looking at an edge
[% END %]

[% WRAPPER 'figure.tt' pic='img_0984' alt="half-die, upside-down" %]
Half of the die, upside-down. It rolls well enough, after a little sanding
[% END %]

[% WRAPPER 'figure.tt' pic='img_0985' alt="half-die, from the top" %]
Half of the die, seen from the top: it's a very good approximation of
a circle
[% END %]

Sadly, the two halves have warped a bit during printing, and it will
not be easy to glue them in such a way as to keep them "round".
