More akiyuki modules?

This model is very cool , are the GBC 10 model can you complete build it ? i still cannot complete GBC 10 model which parts you have't use this this model . very hard to turn the Balls go into the CROSS . and very hard to make the BALLS drop into the tunnel

did a single 42042 model cut it for both GBC 13 and 10 models or did you need to use other parts?

This is great but, it doesn't fit the gbc standard as that requires a module can move 1 ball per second
