This is a dice tower, tray and storage combo. It is based on the model designed by platcham.
The drawer can fit the 7 types of dice (d4, d6, d10, d100, d12 and d20) of a standard dice set. You may be able to fit up to 7 dice of each type in the drawer. It barely fit with my custom dice.
The holes in the models are designed for magnets. They keep the tower-halves together during use and hold the drawer closed. To install the magnets reference the pictures for their polarity.
Make sure to put the drawer in the lower tray before gluing the top and bottom half of the tray together.
If you want you can add a felt of 2mm thickness to the rolling tray. The size of the rolling area is 189.6x160.9 mm. I recommend cutting the felt shorter on each side to reduce the risk of wrinkles during install.
