The “gemstones” in these bracelets are captive, meaning that once printed they rotate freely within the band. Gemstones come in two styles, facete...d and cabochon (smooth). There are three sizes of bracelets, see below for details.
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
Please note that this page is closing, and designs are not being maintained or updated. There have just been too many problems with Thingiverse (lost files, people not able to download, etc).
I am gradually moving over to Thangs: https://thangs.com/designer/DaveMakesStuff. Most old designs have been migrated, and I will continue to post new designs there. I encourage you to follow and download!
