The outer radius sets the washer size and the inner radius sets the center hole. The inner radius must be smaller and leave at least 0.1 mm of wall.
An inner radius of 0 creates a solid disc rather than a washer. Enter a value greater than 0 for a center hole.
A thicker washer is stronger but uses more material and print time. Common washer thickness is 1–5 mm.
Yes. If the inner radius is too large, it is clamped to the available range.
PETG, ABS, nylon, and TPU all work for washers. Choose based on load and environmental requirements.
Yes. The model sits on Z=0 in millimeters and can be imported directly into a slicer.
