Hexayurt Crown

This is the "crown" of the hexayurt. It goes on the bottom, to act as support.

There are 24 3.5mm diameter holes included in the model for wood screws or bolts or whatever. For foam board, I would suggest M3 bolts with big-ass washers on top (against the foam), and little-ass washers on the bottom (against the plastic).

For plywood, I would suggest wood screws with small-ass washers on the bottom (against the plastic).

If you want, you can scale this up to 200mm x 200mm, and it shouldn't effect the operation of the piece. You could then use M4 bolts and would have a bit more strength/stability.
