Hello Tildes board gamers!

I got a 3D printer last year, and over the last few months, I've started printing organizers other people have designed from Printables and Thingiverse, especially for games with poor provided organization or lots of tokens and cards... however there are a number of games I have where people haven't designed a good organizer, or the ones which exist are lacking in some way (don't fit my boxes, missing boxes for expansions, only support all the expansions, etc)

Does anyone have tips on getting started with designing my own? I've got some very basic 3D modeling knowledge, but my primary strengths are as a programmer, so leveraging something like OpenSCAD would be ideal. I saw the boardgame insert toolkit, but it seems relatively basic - there are lots of convenience features I'd love to add as well (like curved walls for token holders to make it easier to get tokens out). Is that a good place to start, or should I look elsewhere?

Even just some ideas about tolerances and/or tips for how to size sections for cards would be super helpful.

So I'm running a D&D 5e campaign, and so far have been doing "theatre of the mind". But it has it's limitations when I want the players to use actual combat strategy in some areas. I have experience a few years ago with using a 25mm paper grid for 3.5e and Pathfinder, which worked well because it was quick to draw a map with whiteboard marker.

Now I have a 3D printer, and I'm wondering if anyone has any dungeon tile recommendations, considering the following:

Firstly, are there any systems that are quick to assemble/disassemble as the players discover new rooms, or we need to clear table space?

Second, stability of the map is important. If a player knocks the map with their hand, will everything collapse, simply shift slightly, or is it rigidly held together?

Third, community: A larger community that contributes (and takes contributions) would be better than a propriety system that doesn't allow homebrew designs.

I've seen a few systems (openlock, openforge, and almost any keyword combination that I can think of is on kickstarter), but I'm finding it hard to get a feel for how popular the systems are, and how well they actually work when on the table.

Does anyone have any recommendations on a good system? I guess i'm most interested in the game flowing smoothly, but I'm not opposed to going to a blank paper grid if that's really the better solution.
