A quick progress update - I just amended the Maker World page with a new template for regular size Plarail compatible tracks but this one intended to be printed with AMS enabled printers (at least four colours).
One new addition to the customiser is the option for either cylindrical or cube magnet cavities. I've found with the tiny 3mm diameter rounded magnets, they can be press fit into the ends of the track bed and provide a much better joint with magnet-to-magnet connections and no intervening filament or cover.
