Two pieces were modeled to go inside a plastic jar and act as the supporting pieces for the compass spinner. The bottom piece was meant to hold an aluminum rivet straight up inside the jar which didn’t have a flat bottom. The top piece was meant to be screwed into the jar’s lid where it would hold the spinner down and keep a protrusion in place for the spinner to tap against.
When the jar inserts were printed the base would not fit inside jar as planned. In order to reduce the diameter of the base a cordless drill was used to rub the base on sandpaper. Reducing the diameter this way produced a smooth and uniform edge without having to reprint.
The pieces were all set together to show off how they were intended to fit together. The aluminum rivet was trimmed so it would fit the height of the jar before being inserted in the base. The hole in the printed base had to be drilled out in order to closely match the rivet.
All the pieces were assembled. Naturally, issues were expected and found. The uneven bottom of the jar wasn’t accounted for so the little legs on the edge of the base were lengthened. The rest of the problems were saved for another revision.

Using a drill to sand the sides of the base

Spinner, base and lid
All the pieces were assembled. Naturally, issues were expected and found. The uneven bottom of the jar wasn’t accounted for so the little legs on the edge of the base were lengthened. The rest of the problems were saved for another revision.
Assembled in jar
