I'm looking into doing a semi-custom 3D printed objective room. I know that there are 'official' options (mostly made of MDF) and the ITS rules state that the room should cover an area of 8" by 8". My question is how much of a stickler most people are for objective room size and shape. Is it the exterior width of the room that should be 8" or the interior width? For example, if the Objective room is exactly 8" across but the wall thickness means the inside of the room is 7", is that a problem? If the outer walls are slightly curved around the edges, is that a problem? Regarding the doors, I'm under the impression that all Objective Room doors are being treated as 'Wide Gates' for movement purposes. I realize that the opening can technically be any size, but is there an opinion on whether a 'double door' size entrance works better than a 'single' for something like this in terms of LoF and tabletop usage? Also are there circumstances where doors that are perpendicular to one another are wide/narrow gates respectively (e.g. north south entrances are wide and east west entrances narrow?) For friendly games I don't have an issue playing my own way but if I bust out an objective room in the wild, I want to make sure people won't get mad at me.
