This is a robust, replacement snap-in dishwasher rack wheel designed to restore smooth operation to your appliance's sliding racks. Over time, factory dishwasher wheels are notorious for becoming brittle, cracking, or snapping off entirely due to constant exposure to high heat, harsh detergents, and heavy dish loads. This model serves as a direct, cost-effective substitute for OEM parts.

Intended Use & Functionality

• Smooth Gliding: Designed with a clean, low-friction profile to ensure the rack rolls smoothly along the dishwasher's metal tracks without binding.
• Snap-In Design: Replicates the standard factory snap-fit mounting style. It features an integrated central hub axle that pushes directly onto the existing rack stud or housing, securing it in place without needing separate hardware or pins.
• Universal Brand Compatibility: Engineered to fit a wide variety of standard models from major manufacturers sharing the same hub dimensions, including Whirlpool, Kenmore, and KitchenAid.

Print & Material Recommendations

Because a dishwasher is an incredibly harsh environment, material selection is critical for this part to last:

• Material: Do not use standard PLA, as it will deform and fail during the first hot wash or heated dry cycle. To ensure this wheel can easily handle the intense heat and aggressive chemical environment, this part was successfully printed and tested in carbon-fiber reinforced nylon (PA6-20CF). Utilizing a high-performance filament like PA6-20CF provides the exceptional heat deflection and mechanical strength required for long-term durability.
• Infill & Walls: Print with at least 4 to 6 perimeters (walls) and a high infill density (40% or higher, or solid 100%) to ensure the snap-fit axle hub has enough structural integrity and spring tension to snap into place without shearing.
• Orientation: Print flat on the build plate for optimal dimensional accuracy of the rolling surface and maximum strength across the snap-fit retention tabs.
