This is a scale model for a large out-door sculpture. It is a twisted and flared 5-story Scherk tower with 3rd-order saddles.
This design and fabrication effort 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.
In the .STL file describing this part, the contours from different surfaces (e.g. around the equator) have not been merged -- but the cracks should be very small. Thus this requires software that does some polygon closing across small gaps automatically.
The compressed files can be downloaded from our anonymous FTP
site with:
ftp ftp.cs.berkeley.edu {login as "anonymous"; use your full
e-mail address as password.}
Then change directory: cd ucb/projects/unigrafix/STL99
Fetch desired file: get FILE.stl.gz
The FILE.stl.gz file can be uncompressed with gunzip.
