Micro Prop Cutter/Trimmer

thingiverse

This tool cuts down small propellers to precise sizes, handling propellers with a radius of 14 to 59 mm and an axle diameter under 5 mm. Its design allows for interchangeable adapters, accommodating various axle diameters while also enabling the height adjustment to match the space required by the nail cutter. A threaded version requires specialized tools like threading equipment and screw taps. However, an alternative version is available that doesn't need adapters - it works with a fixed object such as a nail or needle serving as the prop axle. This tool needs a compatible nail cutter, as described in the PDF documentation.
