Unfortunately I haven’t progressed my scripts to a state where they are suitable for sharing.
My aim was to create a ‘print queue’ - which would manage a list of ‘to print’ objects - and then automatically select the right ones to match the print in question - working out which object best matched the objects to be printed in terms of layers where colour changes happened etc.
More recently I have focussed more on just manually adding parts of my purge table, or just letting the purge happen and then melting it into flat sheets.
If I ever get back to working on this - I think what I will want to do is create a post processor that firstly selects ideal objects for flushing into - plus also modifies the gcode to move the Z position up or down a little bit - so that the flush objects ideally don’t add any additional time to the prints.
