Parametric Spur Gear M0.5 (20 Teeth) - Solid Core Mechanical Replacement Part

A high-precision, 3D printable parametric spur gear engineered as a reliable mechanical component or replacement part for robotics, small actuators, and custom hobby projects. This model follows precise involute profile mathematics to ensure smooth power transmission, minimal friction, and optimal tooth mesh engagement.  The gear's geometry is fully defined by the following technical parameters: - Module: 0.5 mm - Number of Teeth: 20 - Pressure Angle: 20° - Gear Length (Face Width): 4 mm - Profile Shift: 0 - Hole Type: None (Solid core) Designed with a solid core, this asset serves as a versatile blank canvas, allowing makers to easily subtract their custom shaft bores (squared, hexagonal, circular, or keyway slots) directly within their slicer or CAD modifier tools. Files included for reference: - image_4cc0ce.png / image_4cc111.png: Full parametric generator specifications and Romanian translation charts confirming the structural inputs. - image_4cc3f2.png: Slicer software integration preview demonstrating optimal layer paths, an "Aligned" seam placement strategy to safeguard tooth flauks from artifacts, and clear dimensional layout on a smooth plate. - image_4cc419.png: The clean, untextured clay render of the manifold mesh showcasing pristine geometric symmetry. Recommended Printing Settings: - Layer Height: 0.08mm Standard (Highly recommended as shown in slices to capture the microscopic resolution of the M0.5 tooth profile curves) - Nozzle size: 0.4mm (A 0.2mm nozzle can be used for even finer dimensional tolerances) - Orientation: Flat on the build plate (Default layout) - Supports: No - Seam Position: Aligned - Perimeters/Walls: 4 to 6 layers (Crucial for maximizing tooth shearing strength under load) - Filament Choice: Generic PETG (for optimal toughness and low friction wear), Nylon, or Tough PLA.
