Hobbyists, robotics builders, and small-machine designers who need a reliable 1 Mod 17-tooth spur gear will find this blue nylon stepped-bore pinion a practical, drop-in solution.\u003c\/p\u003e\n    \u003cp\u003eEach gear is machined from engineering-grade blue nylon (PA66 or equivalent), offering a good balance of rigidity and self-lubricating properties. The module is 1 (Mod 1), tooth count is 17T, and the stepped bore accommodates 4 mm, 5 mm, or 6 mm shafts — spanning roughly 0.157 in to 0.236 in. Overall gear diameter is typically 19 mm (≈ 0.75 in) with a face width in the range of 10–15 mm (≈ 0.39–0.59 in).\u003c\/p\u003e\n    \u003cp\u003eTypical use cases include: compact DC-motor gearboxes for robotics arms and wheeled platforms, extruder drive trains in FDM 3D printers requiring low-noise plastic-to-plastic meshing, and light-duty conveyor or indexing mechanisms where a 1 mod 17 tooth nylon pinion gear reduces system weight and eliminates the need for lubrication.\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\u003eCompatibility:\u003c\/strong\u003e Meshes with any Mod 1 (Module 1) spur gear or rack.
