Which models can be easily multiplied by 3D printing from one box?

friends HT and WTH

Hey, I managed to get a friend into warhammer and definitely not on my recommendation he joined forces of hive mind. :Ddd Anyway, now he is starting to buy his first models and since I have a printer we are looking for tyranid models where it is possible to reprint a smaller part of the model and multiply the amount of models from one box.

I knew that you can do this with a hive tyrant where you just reprint the body and you have two models from the box at once, but I don't know of many more models. So I'm relying on the collective wisdom of the hive mind in my search. Ideally less than 50% of the model would need to be printed, to pass rules of our local game store, for tournament play, however this is for the future and we are taking all ideas for now :D
