Precision Involute Gear Modul 0.8 (30T, Ø5mm)
This project features a precisely designed involute spur gear with a fine tooth profile, perfect for applications requiring compact size, high precision, and smooth power transmission.
Overview
This gear is engineered for small-scale mechanical systems, robotics, educational kits, or any application needing a strong yet compact gear ratio. The specific combination of a Modul 0.8 and 30 teeth creates a versatile gear with a standard pressure angle of 20 degrees, designed to mesh flawlessly with other Modul 0.8 gears.

Print Settings
For a gear with such fine teeth, print settings are paramount for functional accuracy. These settings are recommended for the best balance of tooth definition and mechanical strength:
- Printer: Bambu Lab X1C / P1P / P1S (Or any FDM printer calibrated for fine details)
- Plate: Textured PEI Plate recommended (as shown)
- Filament: Tough PLA or PLA Basic for general use; PETG for higher temperature resistance. (Example uses Grey PLA).
- Nozzle: 0.4mm (A 0.2mm nozzle can be used for extreme precision but may increase print time significantly).
- Layer Height: 0.12mm (Recommended for finest tooth profile and smoother meshing).
- Wall Loops: 4-5 (Crucial to ensure the teeth are solid and strong).
- Infill: 100% (Recommended for such a small gear to ensure maximum strength and to prevent internal voids that might cause failure).
- Top/Bottom Layers: 4-5
- Supports: Not required. The gear is designed to be printed flat on the bed.
- Brim: A small brim (e.g., 5mm) is highly recommended for such small parts to improve bed adhesion and prevent warping of the tooth tips.
Assembly & Tolerance Notes
- Bore Tolerance: The 5mm central hole is designed with a very tight tolerance. Due to the nature of 3D printing and material shrinkage (especially with PLA), the hole might be slightly undersized. Be prepared to lightly ream or file the hole for a perfect, secure fit on a 5mm shaft.
- Meshing: For optimal performance, pair this gear with other precisely printed Modul 0.8 gears. Ensure correct center-to-center distance based on the pitch diameter calculation. A small amount of plastic-safe grease will significantly reduce friction and wear.
