About this Object
Based on the common plastic-headed push-pins that we see everywhere.
The shaft of the metal pin extends inside of the plastic, and has a flat
head on it, which is all visible
if rendered semi-transparent (as some of these push pins
The axis of the pin lies on the Z axis, with the pin pointing in the
positive Z direction. The origin goes through the joint between
the metal pin shaft and the plastic pin top, so that it appears pushed
all the way into a plane at Z=0 (hint for using in scenes, pushpins are
never quite pushed
in all the way, and they're never pushed in completely straight).
The pin point is 3/8 units past the origin in the postive Z direction,
and the top of the plastic is 0.465 units in the negative Z direction.
Problems and Future Work
The spherical dome that sits on the top of the pin does not perfectly
match up to the cone it sits on top of.
