Harley Quinn 3D print model

So I am a huge harley fan, but with the endless amount of statues and figures I have I am all about the detail. I see that it comes in separate parts. This is the first time I am printing something like this, with which looks like highly detailed. 1. how do you assemble the pieces? do they slot into each other or do you use some kinda glue? What's the size of this model?

hello, this model is configured to print at a size of 22 cm approx, but you can scale it to the size you like, the model has connection points with inserts, the culaes must be joined with glue, we appreciate your interest. good day.

cool model
