About this 3D model

A sci-fi playing field (floor), the elements of which are interconnected by fastening.2 versions of the playing field (both versions are identical from above, the mounting elements are the same):1 version - more beautiful ends and the reverse side of the field;Version 2 is more economical, less material is needed for printing and more elements can be printed at a time if you put them on the end when printing (I personally prefer the second version).3 fasteners: clamp_4 - for connecting 4 field elements, clamp_2 - for connecting 2 field elements, clamp_1 - for mounting on free corners of field elements.
