HotSpring Cover Lifter Replacement Joint

About the Model

This is a highly accurate, reverse-engineered replacement part for a HotSpring cover lifter pivot joint . The original injection-molded factory parts are notorious for cracking or snapping over time due to constant torque, UV exposure, and heavy loads from water-heavy hot tub covers.

To ensure a perfect fit, this model was created by capturing an original, undamaged component using a high-resolution 3D scanner . The resulting mesh was then clean-aligned, structurally optimized, and reverse-engineered into a solid CAD model to guarantee proper mechanical tolerances, smooth pivot action, and seamless compatibility with the factory hardware.

Recommended Print Settings

Because this is a high-load mechanical joint exposed to constant outdoor elements (UV, moisture, and spa chemicals), material choice and slicing settings are critical:

- Material: PETG , ASA (excellent for UV resistance), or ideally Nylon (PA / PA-CF) for maximum structural strength. Do not use standard PLA, as it will creep, warp under summer heat, and snap under load.

- Perimeters (Wall Count): 4 to 6 lines minimum. (Structural strength comes from solid walls, not infill).

- Infill: 40% to 70% using a strong, multi-directional pattern like Gyroid or Grid .

- Layer Height: 0.2 mm provides a great balance between print time and layer adhesion.

- Supports: [Yes / No — e.g., Yes, Organic/Tree supports are recommended for the underside overhangs ].
