Makes
A parametric tape spool adapter featuring a compliant spring mechanism. This script generates a hub with tangential arms that connect the inner bore to the outer rim, allowing for tolerance compensation and smooth rotation.
This design features a tapered notch to ensure it prints cleanly without supports.
Parameters
Measurements (Calipers)
rod_diameter: Diameter of the mounting rod/dowel (measure the actual object).
spool_inner_diameter: The Inner Diameter of the tape roll where the adapter sits.
tape_width: The exact width of the tape roll.
Tolerances & Fit
rod_clearance: Extra gap added to the rod diameter so it slides easily.
tape_width_clearance: Extra clearance added to the tape width slot so the roll spins freely.
Structural Design
arm_thickness: Thickness of the flexible spring arm walls.
arm_count: Number of spring arms.
arm_sweep_angle: Arm curvature (100-120 is usually best).
center_wall_thickness: Thickness of the solid ring around the center hole.
