Parametric Spur Gear M1.0 (20 Teeth) - Solid Core Precision Pinion Blank

A mechanical-grade, 3D printable parametric spur gear engineered as a robust pinion or replacement transmission component for mechanical systems, custom robotics actuators, educational gear trains, and DIY engineering projects. This asset relies on exact involute profile mathematics to guarantee smooth power transmission, uniform stress distribution along the root fillet, and highly efficient tooth mesh engagement under continuous load.

The gear's geometry is fully defined by the following precise parametric inputs:

- Module (Modul): 1.0 mm

- Number of Teeth (Numărul de dinți): 20

- Pressure Angle (Unghiul de presiune): 20°

- Gear Length (Lungimea angrenajului / Face Width): 8 mm

- Profile Shift (Schimbare profil): 0

- Hole Type (Tipul găurii): None (Solid core blank)

Designed as a solid core blank, this component serves as a versatile baseline asset for mechanical alterations. It allows engineers and makers to cleanly subtract custom shaft diameters, squared driving hubs, hexagonal key patterns, or standardized keyway slots using modifier shapes inside their slicer or native CAD software before manufacturing.

Recommended Printing Settings:

- Layer Height: 0.12mm - 0.16mm (Suggested to capture the exact evolventic curvature of the module 1.0 tooth profiles and ensure tight dimensional tolerances)

- Orientation: Flat on the print bed (Default layout).

- Supports: No (100% supportless design).

- Seam Position: Set to Aligned.

- Perimeters/Walls: 4 to 6 layers minimum (Crucial to build maximum shearing resistance across the gear teeth and enforce structural rigidity under load).

- Filament Choice: Tough PLA+, Generic PETG (ideal for low friction and wear resistance), ABS, ASA, or Nylon.
