I wanna make custom spec spring wire diameter : 0.9mm OD : 6.5 free length : 130 number of active coil : 24 Do you need this file to make SpringDesigner.scad ? Or SpringFactory.scad? When I opened SpringDesigner.scad, only this background came out. <img width="732" alt="Image" src="https://github.com/user-attachments/assets/473cd28f-2d39-482c-be48-ec9f33caea0c" />
