The default inner diameter is 22mm. You can scale the model uniformly to fit your finger size.

* Formula: Target Size / 22 = Scaling Factor.

* Example: For a 20mm finger size, scale to 90.91%. For a 16mm size, scale to 72.73%.

* Technical Note: Supports might be applied, thorough post-processing (sanding and polishing) is highly recommended for a smooth, premium finish. Because the ring is small and printed on an FDM printer, surface quality has limitations — do not expect flawless results like actual ring. For noticeably better detail and texture, we recommend using a 0.2mm nozzle.
