The faceted “gemstones” in these bracelets are captive, meaning that once printed they rotate freely within the band.

This design is particularly suited to printing with multicolour filament as rotating the gemstones allows for visualization of the different filament colours.

Once printed, allow the print to cool. Wiggle each gem back and forth until it breaks from the small internal supports. Twist it a few times until it turns smoothly.

The inner diameter of each bracelet is as follows: 24 Gemstones: 90mm 20 Gemstones: 75mm 16 Gemstones: 60mm
