The prompt
Design a parametric 3D-printable LED holder for a climbing wall. Requirements: - The climbing wall panel has an 8 mm diameter hole. - The holder must be inserted from the back of the panel. - The front section must fit tightly into the 8 mm hole (7.8-7.9 mm outer diameter for press fit). - The holder must include a rear flange to prevent it from passing through the hole. - The holder must keep a 12 mm WS2811 LED pixel perfectly centered and perpendicular to the panel. - The LED must snap into the holder using flexible clips, without glue. - The LED lens should remain approximately 2 mm behind the front surface of the panel. - Include a tapered internal light guide between the LED and the front hole to maximize light output and reduce light leakage. - The part should be optimized for FDM 3D printing in PETG. - Wall thickness: 2 mm. - Add small chamfers where appropriate. - The design should be fully parametric so the hole diameter, LED diameter and panel thickness can be changed later. Output as a parametric STEP model.
