Only a minor change was done to the spinner. A groove was removed from the bottom. Its purpose was to allow a screw, protruding from below, to pass under the spinner as it rotated. When the spinner faced north the wobbling effect would allow for a metal-on-metal collision between the screw and magnet. Currently the metal-on-metal collision will also take place when facing south.
The base received three changes. The first change was to make the central post identical to the test base which make wobbling on at the poles possible. Secondly, a hole was added to add a brass screw through the bottom. A screw will be used so the height can be adjusted while testing. The last change was to add fastening holes around the outside so a top can be modeled later and enclose the entire project.
