About this Object
This is based on the Noseman magnet made by Adams Manufacturing.
The "underside" of this magnet is not there. You can't see this in
the above view, but the nose is wider at the base than at the top or the tip.
The magnet is oriented to stick to a wall in the X-Y plane at Z=0, protruding
out in the -Z direction, and is centered around the Z axis. This is shown
in the picture above. The magnet body is 1.6 units in
diameter, and the round part protrudes 3/8 units in the -Z direction from
the "wall". The nose extends out to 1 and 1/8 units -Z.
Problems and Future Work
The back of this magnet should be hollow, with plastic box that holds a
metal cage, a magnet, and a clear plastic clip that holds it together.
None of this has been modelled. All of this stuff on the underside causes
the plastic front to sit almost an eight of an inch off the surface, so the
origin should to be moved to compensate for that.
The join between the slant and the round of the nose is not mathematically
correct, and a seam is visible there. On the real object the bridge of
the nose is not flat, but curves inward slightly. The nose as modelled
is not rounded on the edges. The real magnet has slight depressions
around the eyes. None of the flat parts are totally flat in the real
magnet (this could probably be handled with a texture).
