Whirlpool Washer Timer Knob Replacement (WP8538949)

Restore your washing machine’s functionality with this precision-engineered replacement knob. Designed to replace the often-broken WP8538949 (and compatible parts), this model features a reinforced internal D-shaft to ensure a snug fit and long-lasting durability against daily wear and tear.

Key Features:

• Perfect Compatibility: Fits a wide range of Whirlpool, Kenmore, and Roper top-load washers.
• Reinforced Design: Optimized geometry to handle the "pull-to-start" and "push-to-stop" mechanical stress better than the original plastic part.
• Easy Assembly: Designed to be used with the original decorative metal/plastic cap for an OEM look.
• Print-Ready: Optimized for FDM printing with minimal cleanup.

Printing Recommendations:

• Material: PETG or ASA recommended for heat and chemical resistance (PLA works but may degrade over time in laundry environments).
• Infill: 40-60% (Gyroid) for maximum structural integrity of the shaft.
• Walls: 3 to 4 perimeters for a solid feel.
• Layer Height: 0.16mm or 0.20mm for a smooth finish.
