Lets say I have a model which I want to print in a size my 3d printer can't print.
Let's say it's 12'' and the 3d printer prints at 6''.
The only option is to separate the model into smaller pieces, print those and then stick them together somehow.



Then I could glue them together and finish the final object.

For a simple sphere like this I can easily do that myself, but I'd like to know if there is any program or plugin for a program, for general 3d modelling or for 3d printing specifically, that can separate an object into chunks automatically from some input like size of chunk.

What would be even better and maybe it will sound too much to ask for this, but will totally make sense to exist by now, is a plugin or program which will not only separate a model into pieces, but also generate holes and poles on the chunks so you can stick the chunks into each other:


I think cyancrylate glue would be best to turn the printed chunks into one object, but it might not be strong enough by itself.
