A print was made which was rotated 180º compared to the previous prints. Previous prints were made differently to ensure that the pivot point was printed on top and therefore would be less likely to have printer errors. Unfortunately this design was unable to print well in this orientation. Printer errors were easily noticeable and the print was unacceptable.
The spinner was split into two segments, the cap, which contained the pivot point, and the bottom which contained the magnets. This split ensured a clean surface on the pivot point and the area where the screw will pass over.
Splitting the model meant that the two halves had to be glued together. A metal chopstick was used to center the cap. The chopstick’s diameter and rounded tip allowed it to align the two halves.
A lid with a screw hole was also printed and a screw was inserted. The screw was inserted far enough to collide with the magnets when facing north or south but the spinner would not reach the screw when facing any other direction. The screw was replaced with a bolt so it could be adjusted more finely.

Printer anomalies on spinner
The spinner was split into two segments, the cap, which contained the pivot point, and the bottom which contained the magnets. This split ensured a clean surface on the pivot point and the area where the screw will pass over.
Printed with separated cap
Splitting the model meant that the two halves had to be glued together. A metal chopstick was used to center the cap. The chopstick’s diameter and rounded tip allowed it to align the two halves.
Cap glued in place
A lid with a screw hole was also printed and a screw was inserted. The screw was inserted far enough to collide with the magnets when facing north or south but the spinner would not reach the screw when facing any other direction. The screw was replaced with a bolt so it could be adjusted more finely.
