The prompt
I have a **RingConn Gen 2, size 10**, but after losing weight, it became too loose. I tested a **size 9**, and the fit was perfect. I currently use a small amount of silicone inside the ring to make it tighter, but it eventually comes loose or forms lumps. I would like to replace it with a small **3D-printed inner spacer**. ### Design requirements - The spacer must be installed **only on the upper inner section of the ring**. - It should be a **small curved arc following the inner curvature of the ring**. - It should cover **less than 1/4 of the inner circumference**. - It should be centered at the top, with the sides and bottom of the ring completely free. - It should be low-profile, smooth, and comfortable against the finger. - All edges should be rounded. - It must not interfere with the RingConn sensors or charging contacts. - It should provide enough thickness to make the size 10 fit similarly to a size 9. - It should be attachable with a small amount of adhesive. - Ideally, it should be removable without damaging the ring. ### 3D printing The part will be printed on a **Bambu Lab A1 Mini**, preferably using **TPU** or another suitable flexible material. Please make the model **parametric**, so the following can be easily adjusted: - Spacer thickness - Arc length - Width - Inner curvature Ideally, provide **3 thickness variants** for testing. ### Files Please provide: - STL for printing - STEP or another editable/parametric format I can provide precise measurements, photos, or a 3D model of the RingConn if needed. **The goal is a small, discreet upper inner spacer — not a full inner ring or a half-circumference insert.**
