Edit 3: For some reason, the length of each component on each side was inconsistent, but I've already fixed the problem.

Edit 2: All file formats have been unified to STL instead of OBJ, as some slicing software cannot recognize the OBJ format.

Editor: Oh no, I messed up! There was a mistake in the size settings earlier, but it should be fine now! There's no need to adjust the sizes of these components anymore!

I cut the Sheka slate into several small pieces for use by small and medium-sized printers that cannot print the entire slate in one go. The size of each piece has been carefully adjusted. If the actual size deviates slightly from the expected one, it is recommended to adjust the length of all components to 120 mm, so that the total length of the entire slate reaches 240 mm.
