Pair-of-pants surface

Here is a pair-of-pants surface designed for the InforMath project funded by the National Science Foundation (DRL-1323587). The InforMath project (http://informalmathematics.org/) is a partnership between San Diego State University and several museums at the Balboa Park, including the Reuben H. Fleet Science Center (http://www.rhfleet.org/)

These models are designed to join together using small magnets. There are two options for the print files, ones with small holes for the magnets and ones without. There is a ring system too, so that you have more flexibility in how the models are put together. There are also thin versions of the models (with no magnet holes).

More information about the models, including how they were designed can be found at http://mathvis.academic.wlu.edu/2016/02/09/constructing-a-pair-of-pants/ and http://mathvis.academic.wlu.edu/2016/02/09/pair-of-pants-surfaces-the-math/.
