The place for the compass spinner to rest was simply left as a hole which may be useful later but the first model will need divots. The first logical shape was a hollow cone. The cone will guide a spinner directly to the center which will ensure accurate positioning. The worry is that the steep, sharp edges of the cone will introduce a lot of friction. Ideally the spinner would be a sharp point meeting a blunt surface since the sharp point will not have a lot of friction, similar to an overturned tea cup balanced on a knitting needle.
