A simple spider for a small three-jaw lathe chuck. Lathe spiders are used to index parts longitudinally in the chuck or to index thin work pieces perpendicular to the spindle axis (or on a parallel plane to the face of the chuck). Printed in PLA with .25mm layers. This small spider was made for small parts with diameters down to about 5.2mm. Could be scaled up or down, of course, to meet your needs.
