surgical instrument 3d model

Generate a high-resolution, monochrome, blueprint-style technical drawing of an airfoil blade based on the Selig S1223 profile. The drawing must show the blade from a top view and side view. The airfoil must be scaled accurately with a chord length of (pon la cuerda que elegiste: 3 cm, 3.5 cm o 4 cm). The blade should have a total length of 30 cm, with a gentle twist from 7° at the root to 3° at the tip. Replace the typical cylindrical hub mounting section with a flat root section: add a rectangular flat base of exactly 1.5 cm of chord at the root, perfectly flat and uncurved, integrated into the airfoil shape. This flat base must be clearly shown, dimensioned, and designed specifically for screw mounting onto a wooden circular disk (no tube, no hub connector). Include small marked holes for screws (3 holes evenly spaced). Show all measurements, including chord length, blade length, maximum thickness position (12.3% at 25% chord), and twist angles. The style must be clean, engineering-blueprint, printable i
