perforated cylinder 3d model

Create a 3D-printable hollow cylinder (tube) with an outer diameter of 74 mm, an inner diameter of 70 mm (2 mm wall thickness), and a height of 30 mm. Add multiple evenly spaced circular holes with a diameter of 6 mm on the top face, the bottom face, and around the side wall (perforated pattern). The model should be clean, manifold, and suitable for FDM 3D printing as an STL file.
