The actual picture from the album is the base vault and the separate spell tracker. I posted the picture on reddit and people started suggesting I edit the spell slot tracker to be a "top" to the vault instead of something separate, and it's finally here!
The goal of this is to use the dice vault as a base to put 3 sets of dice in, then you can print the spell slot version of the top (and hold tokens in the pit) or print the generic top (and hold a miniature in the pit). Either way, all pieces have a slot in each corner you can insert a magnet into. Once the magnet is in you can put the magnet plug in and superglue it. The max magnet size used by the original design was .3 inches x .11 inches. If you don't like the magnet setup there's now a peg/hole vertical setup.
Lastly there's a tray that you can put the whole thing in. The tray in is as a full item and also as an object split in two. This is because the printer I tend to use is an Ultimaker and the tray itself doesn't fit on the bed and must be printed in two different pieces.
This project is a remix of two different projects. The dice tray is from Aethernex and the spell slot tracker is from justuspr. If you have any problems with it let me know, more than happy to make updated!
EDIT 5/31/2018: Forgot to add tolerance into account when creating the smaller version of the vault/tracker. Should be good now.
Same settings for the Ultimaker 3 and the Ultimaker 2+.
I took the base models from the other projects that this is a remix of and edited them in TinkerCAD. I do this on the side for fun so don't expect perfection.
