This is a insert for Back To The Future Back In Time, it fits everything including sleeved cards* and the dice tower without the need to tear it down.
Instructions: 1. Print 2 Tower Holder and 1 of everything else. 2. Use the Connector to connect the 2 Tower Holder Pieces (I made those pieces so the dice tower wouldn't be crushed by the other boxes and to keep it from moving too much). 3. Place everything in the box according to the pictures.
I changed where the Biff tokens go from the pictures, so there's a new spot on the Dice and Tokens box.
The board sits on top of the dice tower, it's the only way the box can close properly, I like putting the rulebook on the other side below the board to help with that, but it should be fine.
* I sleeved most of my cards, I know the item cards fit there sleeved, but I'm not sure about the trouble cards.
