Ian Friedman: Self-Intersecting Moebius Strip

For the final project, I fabricated a self-intersecting moebius strip.

The final fabricated component was generated by a parametric model that I made using only native grasshopper components.

In the parametric model, the number of holes and size of the moebius strip can be altered.

Also included in the attached grasshopper file is a non-intersecting parametric moebius strip model, where width and number of twists can be modified, as well as the path that the moebius strip follows.

To make the single surface model into a printable file, I had to offset the surface and manually (in Rhino) loft between the holes and the boundary curves.

I then converted to a mesh, which didn't actually result in a good mesh. I then uploaded my mesh into makeprintable.com, which turned my non-functional mesh into a beautiful, printable stl file.

From there, I sent the stl to a 3dSystems projet 360 powder printer in the CMU School of Architecture Digital Fabrication lab where it printed in approximately 2.5 hours.
