The base designed for yesterday's spinner needed the nails to be much closer together. In fact, they wound up touching each other they were so close. Printing produced a single hole with a shape roughly resembling three holes close to one another.

The shape of the hole can be seem if viewed in high resolution

A small drill bit was used to open the holes to the correct size. The central nail, which the spinner rested on, had to have the sides trimmed then compressed in order to fit all three nails in place. Flush cutting pliers were used to trim the sides and ordinary pliers were used to flatten/crimp the sides.

Spinner with three nails installed

Superglue was used to hold all three nails in place. Tension had been enough in previous models but this version lost much of the supporting plastic when installing the nails so close to one another. The compass performed well. The spinner would spin freely and wobble the most at north or south.
