3D Disc for A1 - "Ultraball"

This is a small evolution of my other Pokéball design     Now the red part can be replaced with the black and yellow part of the Ultraball. Due to the way of assembly of the V1 it did not allow the yellow parts to be inserted, so the insertion has been modified to the central part.     You can also use the included red part in case someone wants to play with the pieces without changing the rest of the parts. I could have left the central area and the black upper part in the same piece, but if I did so it would nullify the possibility of changing to the red part.     The model has been tested in PLA, with the gold textured PEI and the chameleon hotbeds and the assembly is perfect like the previous model.   Remember: As you know, the main problem with these multicolor prints with AMS is the loss of time in changing filament and the number of grams that are wasted, so I have designed this pokéball in such a way that it can be printed in several pieces to be assembled later. This also allows the layer height to be reduced and the curvature to have a high quality.   Since it is such a small model, I think it is the best option, but if not, I also added the one-piece model.     Please keep in mind that since they are very small pieces, the calibration and adjustment of the bed is very important, since any slight error will not allow correct assembly.   It's also not worth adding brim or elements that can vary the tiny size of the initial layer, so if you don't get it on the first print, try again! ^^
