Computer simulation of the strong interaction part of the Standard Model is a big research area: you may want to read about lattice QCD. I’ve written a simple lattice QCD simulation in a few hundred lines of code. If you Google a bit you can probably find some example code. The rest of the Standard Model has essentially the same structure and would only be a few more lines of code.
Assuming you’re right about it only being a few more lines of code, and that you didn’t use a lot of external libraries, that puts an upper bound at… a few dozen kilobits? I’m guessing that could be made a lot smaller, since you were likely not focused on minimizing the lines of code at all costs.
