🔷 Stackable 1:2 Helical Gearbox
This is a compact stackable helical gearbox module with a 1:2 gear ratio, designed for smooth motion transfer and easy expansion into multi-stage gear systems.

🔷 Modular Sandwich Design
The gearbox uses two outer frame plates that hold the gears in position. Multiple modules can be connected in series, allowing you to build larger transmission setups with several gear stages.

🔷 Helical Gear System
The angled teeth provide smoother meshing compared to straight gears, helping to reduce noise and improve load distribution during operation.

🔷 1:2 Ratio per Module
Each gearbox stage provides a 1:2 transmission ratio. By stacking several modules, higher total ratios can be created depending on the setup.

🔷 Integrated Shaft Geometry
The gears feature integrated shaft connections with a star-style drive profile, making assembly simple and allowing the modules to transfer rotation between stages.

🔷 Open Frame Construction
The cutout frame keeps the design lightweight while still providing stability. It also makes the gear movement visible, which is great for wear assesment.

🔷 Easy Assembly
The exploded views show a simple part layout with two frame plates and the gear set in between. The design is made to be easy to understand, assemble, and expand.

🔷 Applications
Perfect for mechanical demonstrations, educational models, prototype drives, robotics projects, or as a modular building block for custom gear systems.
