V-slot wheel cleaner

thingiverse

This handy tool helps keep classic 23.9 mm diameter wheels, commonly found on Creality printers, spotless. Simply place it on the rail, guide the carriage towards the cleaner with a gentle push, and move it 8 cm forward – that's all you need to do. This accessory works in both directions, even though the flat part of the wheel is less likely to get dirty. For wheels that are harder to reach, such as those underneath the Ender 3 plate, there's a longer version available.
