At this point, I began to continue to build the model, and then superimposed different structures on it, and began to drill and assemble, and then added some reasonable baffles after considering the movability. At this point, I found that there were some places that could not be successfully drilled when punching holes, so I began to look for the reason. As soon as I opened I checked whether the model was broken, so I deleted the small cylinder and then rebuilt the cylinder to punch holes, but it still showed an error. So I checked the fanal, and indeed found an error. The red part he showed showed that his fan was reversed. Although there are only a few simple words here, in fact, it took me almost several hours to correct this mistake. I recalculated the error of correcting the direction of the fanal, which shows that I need to pay more attention to its direction when I build the model next time, because it will be very troublesome to adjust it later.
