Tamiya 70212 Cross Universal Arm Set - Modder Friendly Pack  [70212]

Tamiya 70212 Cross Universal Arm Parts for Creative Modding

The Tamiya 70212 Cross Universal Arm Set provides a compact, adaptable selection of parts for model enthusiasts and gadget builders. Its flexible layout is useful for putting together motorised mechanisms or reinforcing craft projects. The straightforward components make it easy to experiment with different linkages and drive layouts.

Compatibility and Fit Notes

Arms feature hole centres at 5mm intervals so attachments line up cleanly and allow repeatable mounting positions. Cross crank arms and bearings are compatible with 3mm shafts, enabling common shaft-driven linkages without exotic hardware. This makes the set a sensible choice for a range of school and hobby applications.

Shaping and Adapting the Arms

The material is simple to cut for custom shapes, letting builders fashion L pieces or other profiles to suit a build. Modders can trim and re-drill parts to match bespoke link lengths or to clear nearby components, keeping projects compact and tidy.
