3D printing Beyblades advice

I've made a beyblade well I made more than one and Every time I try to print it, It would come out fine but when I try to put it together the piece that holds it together keep breaking off. I am using the Neosarchizo layer for my beyblade but I just can't figure that out so can anyone help me with this please?
My guess is the pieces are too thin causing the weakness or the material isn't strong enough.
Maybe there is a hollow gap somewhere. They can cause things to break.

By the way, I am not sure.
Can you send a pic of the part and the specs of your printer?
