Telescopic Mast with Spacers

Create a 2D mechanical engineering blueprint of a 12-meter telescopic aluminum mast made of 4 sections, each 3.00 meters long with a wall thickness of 2mm. Section 1 (Base): Outer diameter 60mm. Section 2: Outer diameter 55mm. Section 3: Outer diameter 50mm. Section 4 (Top): Outer diameter 45mm. The overlapping (insertion depth) between sections is exactly 35cm, resulting in a total aluminum height of 10.95 meters. Drill holes and attached spacers specification (All holes are 8.5mm in diameter): 1. Connection holes: 1 single through-hole centered at 15cm from the outer edge of each of the 3 overlapping joints. 2. Spacers installation: Draw 3 solid side-mounted spacers, each exactly 60cm long, extending horizontally from the mast. All 3 spacers must be perfectly aligned in the exact same vertical line. Position the 3 spacers (and their corresponding 8.5mm through-holes) at the following exact heights from the ground: first hole at 2.00m (on Section 1), second hole at 6.50m (on Section 3), and third hole at 11.00m (at the very top edge of Section 4). The lower 2.00 meters of Section 1 must remain completely solid and clean with no holes and no spacers. Show clear dimension lines, labels, and heights for both the mast sections and the 60cm spacers on a clean white background.
