A new model was printed which had the screws closer together. The base appears thick but is actually bottom-side-up so that cylinders could be printed which kept the side nails from going as deep as the central nail. This distance should have been much greater because the side nails only needed to be a couple millimeters taller than the base so they were cut off instead.

Base with trimmed nails

A fine degree of control was possible with the side nails so the spinner was revised to have a narrower slot. The spinner print on the left shows a pretty wide slot and not much difference between the round segment and the square segment. The updated spinner on the right shows a clear difference between the circular hole and the straight sides.

Updated spinner and new base

Height on the spinner was reduced so a single pin from the base would be long enough to reach the spinner. It worked well.
