Tamiya 69920 Clear Cross Arm Set for STEM Builders

The Tamiya 69920 Cross Universal Arm Set is a practical component aimed at improving STEM lessons and model construction. Its transparent finish gives clear sight of moving parts, helping students and hobbyists understand mechanism layout while keeping the build neat.

Construction and Specs

The kit contains four 80mm x 80mm cross universal arms, sized for straightforward frame and linkage work. Each arm has 3mm holes arranged at 5mm centres, providing predictable mounting points for plates, gearboxes and other Tamiya parts. This predictable pattern makes it easy to plan and expand projects.

How to Use

The clear material is ideal for integrating LEDs and visual elements into demonstration models, and pairs well with clear Tamiya plates, gearboxes and wheels. Use the holes to mount servos, small motors or sensor brackets when prototyping simple robots or mechanisms.

Workshop Tips

These arms can be trimmed, drilled and painted to suit your build; the material accepts basic hobby paints and adhesives. The set also includes an assortment of screws and spacers to cover common assembly needs, making it convenient for classroom kits and maker benches.
