Hi, I've recently adopted a sort of nested dictionary data model descending from a single global object for my printer: https://github.com/hyperair/deltabob/blob/vslot-upgrade/configuration/delta.scad It sort of works and ends up cleaner in some ways in that modules no longer depend on global variables and do not need to have super-long argument lists, e.g. https://github.com/hyperair/deltabob/blob/vslot-upgrade/effector.scad#L224 But it also ends up with massive amounts of boilerplate to handle option extraction: https://github.com/hyperair/deltabob/blob/vslot-upgrade/lib/effector.scad Perhaps I could write a script to autogenerate the boilerplate bits. -- Kind regards, Loong Jin
