Help with completing my assembly

I recreated all the components in SolidWorks from the Step file. The confusing thing is, I couldn't find any component that could be mated to make a usable jig. The component dimensions are incompatible for mating among themselves.
Attaching the files I have created.

All files are not unloadable in one go. So, another two files

three more files
