Bringing this back up: With us moving to a new apartment, my wife's pregnancy, and our baby girl being born, I had to take a long break from this project, but now I'm back on it and made a lot of progress already.
Designing for a 3D printer is difficult if you don't actually have a printer to test on, so I finally got myself a Creality Ender 3, which seems to be a very fine machine (especially for its sub-$200 price point). I'm still learning the ins and outs of 3D printing, so right now I only ran several smaller test prints of fragments of my Jumanji box:
But this has already taught me a few things that informed my 3D model, which is first and foremost: Make this printable as easily as possible. So I split up the model into several smaller pieces (not as cut up as my test prints above, mind you), so that each can be printed at a good quality. This of course requires glueing a few pieces together, but I've tried to make this as foolproof as possible. Take the main lids for example: The top of the box (with that wonderful main artwork "carving") gets printed separate from the rest of the lid. So both pieces can be printed laying down, without any of those dreaded supports needed. To make alignment of the two halves easy when glueing, I've added holes to both sides which, through small "nubs" (printed separately) line up perfectly. This split approach also allows several slots added to the lids, to make adding magnets easier, and hiding these completely once assembled:
This approach is also true for the compartments in the lids. The dividers are separate pieces, as are the hinges and lids. All pieces slot into each other nicely (that's my goal at least) - they still need to be glued of course, but at least you can't glue them in the wrong place:
To make the hinges on these work easier, my biggest deviation from the movie board is the rounded top of the compartment divider. But the good thing is, with this modular approach, the divider can be swapped out easily. So I might as well design a flat-top one, to which "real" hinges can be added. The pin for these hinges might be a kebab stick (or in case of the Blu-ray sized version a toothpick), but I need to test that out once printed. As you can see the compartment lid also has a hole for a magnet in it, which will then cling to the metal bead or screw added to the inside of the lid.
Many smaller pieces are "slotted" into the main pieces as well:
My other design change from my original idea is the placement of the Blu-ray case. I don't know why I originally wanted to place it on top of the board, so now it'll go beneath it. This has the positive side effect of adding a lot of empty space underneath the playing field, for adding electronics - maybe a tablet or smartphone (in place of the Blu-ray, obviously):
So yeah, things are moving along again.
