Dice insert for ultimate DND box (updated bottom)

Modified the bottom of 77rick77's dice insert to accommodate the notches for both vault bottom and the vault bottom for spell cards of archa91's Ultimate DnD Box.

The vault bottom for spell cards has a longer notch. I also moved the notches at the bottom of the dice insert further from the magnet holes to reduce possible warping. Lastly I changes the sizes of the notches to more precise as a personal preference (less time printing support versus infill).
