Dishwasher Rack Roller Wheel Clip
Replacement upper-rack roller for a dishwasher, with a print-in-place 22 mm wheel (7 mm tread, 27 mm retaining flange) that spins on a captured 8 mm post. Instead of copying a model-specific axle stud, the carriage snaps sideways onto any round rack wire from 4.5 to 5.2 mm diameter (5.6 mm pocket behind a 4.4 mm snap mouth), so it works on older machines where the OEM roller is only sold bundled with a whole rack. Overall 40 x 28 x 22 mm; print in PETG rather than PLA for dishwasher wash temperatures.
