Product Description
There is a compound named tricyclo[4.4.0.0^{3,8}]decane also known as twistane. This model features 13 intersecting twistane units. Do you see all of them? The whole thing  may also be seen as consisting of several identical six-membered rings in twist boat conformation. By the way, how many of those rings are there?

The edges angle used in this model is slightly different from the expected 109,47 degrees. Things fit together when using a  smaller angle  of  approximately 106,83 degrees. The exact value, for those of you who want to know it, is arccos(-11/38). - What a strange value, isn't it remarkable?

Another model, the  Seed Of Twist, is on the same topic of fusing rings. It deals with nine identical four-membered rings. See https://www.shapeways.com/product/VNH8RA4AV/seed-of-twist-pendant
