Custom LEGOs Technic Frame + Gear Rack Set

This model includes a custom LEGOs Technic–compatible frame and a matching gear rack designed to work together for robotics and mechanical builds.

The large Technic frame provides a strong structural base with evenly spaced Technic pin holes, making it easy to integrate with beams, motors, and other Technic components. It is great for building rigid robot bases, mechanisms, or experimental designs.

The gear rack is designed to pair with the frame to create smooth linear motion systems . It can be used with Technic gears to build sliding mechanisms such as elevators, moving arms, rack-and-pinion steering systems, or automated robotics attachments.

Features • LEGOs Technic compatible pin spacing • Large rigid structural frame • Matching gear rack for linear motion • Designed for robotics and mechanical builds • Great for STEM projects and custom machines

Printing Tips • Print flat on the build plate • Supports required • 0.2 mm layer height recommended • PLA or PETG works well

This set is perfect for robotics builders, LEGOs Technic fans, and STEM projects who want a strong frame combined with a rack-and-pinion style motion system.
