The prompt

Plate 1: The Anchor Block Open a new Part file. On the Top Plane, sketch a center rectangle and dimension it to 30 mm x 30 mm. Use Extruded Boss/Base to a depth of 10 mm. Sketch two circles of 3.0 mm diameter on opposite corners of the top face (e.g., 4 mm inset from the edges). Use Extruded Cut (Through All) to create the dowel pin alignment holes. On the top face, sketch a single circle at the exact origin. Dimension this to the precise outer diameter of your 30G needle (approximately 0.31 mm). Use Extruded Cut (Through All). This creates the friction-fit bore for your capillary.
