Modular Gear Kit with Motor Mount

Dive into the fascinating world of mechanics with this Modular Gear Kit, designed for both kids and adults to explore, learn, and have fun! While inspired by the excellent Steven's Cog Kit, this updated version introduces significant enhancements for improved durability, flexibility, and customization.

Key enhancements include:

• Thicker gears with larger teeth for more robust and reliable interconnections, reducing slippage.
• A hexagonal grid frame (vs. the original orthogonal grid) for greater placement flexibility.
• Multiple frame sizes to suit different project needs.
• A provided source file (cog-kit.fcstd) for parameterized customization in FreeCAD.

The kit includes gears with 12, 24, 36, 48, and 60 teeth, along with spacers for experimenting with gear ratios. The hexagonal grid frame allows you to position gears and spacers using the included rods, enabling endless creative possibilities. A dedicated motor mount fits an RF-300 DC motor, bringing your creations to life.

This kit is as educational as it is entertaining, making it perfect for curious minds of all ages!
