Todd Wilder’s mystery box has eight hidden compartments, which must be opened in a specific order.
The ideas for this box came to me a little bit at a time, after my 22-year-old nephew had seen my other boxes on MOCpages and asked me to make a box for him. He wanted me to make another one like my Black Box, but I wanted to do something different. This is the only one of my boxes that is complicated enough for me to have actually built a prototype from parts in my “pile.” For the final design, Lego Digital Designer was an indispensable tool, and I also couldn’t have done this without bricklink.com (and my credit cards!). The six main compartments have to be opened in the order shown. The “key” can be helpful to open the other main compartments, in addition to the center one.
