A Core Themed design which can be used as a spacer between keys or even a necklace piece. The hole diameter is 2mm. Print Settings Rafts: Doesn't Matter Supports: Yes Resolution: 0.1-0.2 Infill: 20% (Recommended) Notes: Be careful when taking it off of the bed because of the joints between the outer and inner loop as they may be brittle but the supports (if you add them) will help or prevent this from happening.
