Involute Gear Modul 3.0 (12T, Ø15mm)

This project features a meticulously designed involute spur gear, optimized for 3D printing. It has been modeled with a 3.0 module to ensure high strength and smooth power transmission for functional mechanical assemblies.

Overview

This is a robust, single-piece gear design ideal for prototyping, robotics, educational models, or replacement parts in DIY machinery. The geometry is based on a true involute tooth profile (20-degree pressure angle), which minimizes friction and noise while maximizing load capacity when meshed with other Modul 3.0 gears.

The generated image shows the exact print quality you can achieve, including realistic layer lines and the matte finish of standard PLA on a textured PEI plate.

Print Settings

For best results and mechanical integrity, please follow these printing guidelines. The model shown in the picture was printed with these settings:

Printer: Bambu Lab X1C / P1P / P1S (Or any FDM printer)
Plate: Textured PEI Plate recommended (as shown)
Filament: PLA Basic (Grey shown) or PETG for higher temperature resistance.
Nozzle: 0.4mm
Layer Height: 0.16mm or 0.20mm (Lower layer heights provide smoother tooth surfaces).
Wall Loops: 3-4 (Crucial for tooth strength).
Infill: 40% - 60% (Grid or Gyroid recommended for strength).
Top/Bottom Layers: 4-5
Supports: Not required. The gear is designed to be printed flat on the bed.
Brim: Generally not required, but use a 5mm outer brim if you experience warping on the tooth tips.

Assembly & Tolerance Notes

Bore Tolerance: The 15mm central hole is designed with a standard 'sliding fit' tolerance (approx. +0.1mm) for standard 15mm shafts. Depending on your printer's calibration, you might need to lightly file or ream the hole for a perfect fit, or apply a drop of retaining compound.
Meshing: This gear must be used with other Modul 3.0 gears. For smooth operation, apply a small amount of plastic-safe grease to the teeth.
