This 1 Mod 30-tooth blue nylon spur gear with a stepped bore is designed for hobbyists, robotics builders, and small-machine designers who need a reliable, corrosion-resistant drive component without the weight or cost of steel.\u003c\/p\u003e\n    \u003cp\u003eEach gear is machined from engineering-grade blue nylon (PA66 or equivalent), offering a good balance of toughness, self-lubrication, and dimensional stability. The module is 1 (Mod 1), tooth count is 30T, and the pitch diameter is 30 mm (≈ 1.18 in). The stepped bore accommodates shaft diameters from 5 mm to 15 mm (0.197 in – 0.591 in), covering the most common motor and shaft sizes used in DIY and light-industrial applications. Overall gear width is typically 10–15 mm (0.39–0.59 in) depending on bore selection.\u003c\/p\u003e\n    \u003cp\u003eTypical use cases include 3D printer extruder drives and Z-axis lead-screw couplings, small robotic arm joints requiring a quiet 1 mod spur gear pinion, and desktop CNC or automation projects needing a lightweight plastic gear with step bore for compact assemblies.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"hdiy-compat\"\u003e\n    \u003cspan class=\"hdiy-compat-icon\"\u003e⚙️\u003c\/span\u003e\n    \u003cstrong\u003eCompatible with:\u003c\/strong\u003e All standard Mod 1 (1M) gear systems — pairs directly with 1M rack, 1M pinion, and 1M mating spur gears.
