Models were updated. The lid was changed to have a cone in place of a hemisphere. The screw hole was thickened to give it a collar which was meant to keep an inserted screw or bolt straight. Spinner design was heavily revised. Instead of a printed cap a new method was conceived. A thin brass strip will be glued over the top then dented upward to form a spot for the post to rest. This should reduce friction between the spinner and post. A metal insert into the post may also become necessary to further reduce friction.

Plastic use was reduced by eliminating unnecessary sides. The hemispherical look was gone but the balancing point should be the same. If a version is printed which uses a liquid medium the sides may be restored to reduce hydro resistance and unwanted currents.
