This is an alternative model, the LEGO group often makes sets with only two models available (A and B), I propose here to build a third model with your box, I mean with the pieces you have, you can build it.What I'm selling here is the full building instructions I created with Studio. There are 215 steps and they are easy to understand.it kind of worked, but stud.io seems to recognise it as just one part, or as in the screenshot, 2 parts. Is there a way I can resolve this? or is it just not the right file type or something
