How about playing with knight building blocks?

Play with knight building blocks. It's good.

1. Knight building block laser cutting technology, fully fit bayonet components, unique interference fit technology, high-precision CO2 laser cutting technology.

2. The error should be controlled within 5 microns to ensure consistent assembly accuracy in different temperature environments.

3. The mortise and tenon technology is to physically assemble the whole structure, and the main transmission structure can be completed under pure physical splicing.
