Part Description and Specifications for
"Monkey Trefoil"
This is a minimal, 3-fold symmetrical version of a 3-storey monkey-saddle
Scherk tower bent into a toroid.

Origin:
This part was generated with Carlo Séquin's
sculpture
generator, using the following settings:
-
branches = 3
-
storeys = 3
-
height = 1.75
-
flange = 1.50
-
twist = 180.00
-
azimuth = 0.00
-
thickness = 0.05
-
rim_bulge = 0.00
-
detail = 16 {--> 39,168 triangles}
Usage
This part will serve as a geometrical model in classes on modeling and
math of minimal surfaces, and as a small scale model for artists, e.g.,
Brent
Collins, who is doing similar sculptures in wood.
This is part of a research program sponsored by NSF to streamline the
process of rapid prototyping of free form parts, by defining a clean separation
and interface between designers and fabricators.
Fabrication Hints
The scale or strength of this model is not critical; it can be scaled so
as to fit optimally a particular process or some remaining space in a run
of a larger piece. The STL files describe a part with a diameter (in x)
of 6.24 units and a thickness (in y) of 3.02 units. The surface walls are
0.1 units thick. Ideally we would like a part scaled to be
3-5 inches
in diameter.
Orientation is not critical either. However, for a layered manufacturing
process (SLA, SLS, etc), it might be best to turn the object 90 degrees
around the x-axis, thereby giving the part minimal height, and preserving
its 3-fold symmetry ideally. Front and back side are different; for SLA,
it might be better to face the "Back"-side downwards.
