This is an insert for the board game Tesseract: an extra-dimensional dice manipulation game. The Stock insert does not have room for both sets of dice, so I mainly developed this to make use of the ample box space. You will need to print two of the dice trays, which I made extra thick due to the weight of the alloy dice. The bottom spacer should be printed with platform/scaffold aligned to your print bed, then turned upside down in the box to give the next layer a bit more support.
The card slots support sleeves, SleeveKings “Mini USA” and “Card Game” sleeves are on display in the pictures above.
