Captive Roller Dice

thingiverse

This unique wooden rolling dice was designed by Barry Lockwood, an English inventor and designer. It is crafted from a single piece of wood with a resin dice at its core. I was fortunate enough to receive this pair as a gift and attempted to recreate the design using 3D printing technology. The model prints in three parts: the body, the dice, and a mounting bar. To assemble it, you will need two high-quality 604 bearings for each die. The good news is that you can print two dice at once, which they fit together seamlessly. To ensure an even distribution of weight, I carefully calculated the size and depth of the face marker holes. This design is divided into two versions: Dice V1 / Bar V1 and Dice V2 / Bar V2. The basic version is easy to print and assemble. Simply push a bearing into one side of the dice, slide the bar in, and then push another bearing onto the other side. The bar and dice have 4mm spacers to keep the bearings separate. The second version features a channel running through the center of the die. If you place a ball bearing in this channel, it will ensure that a flat face is always facing upwards. However, this requires some additional design changes, making the bar harder to print. To assemble the second version: 1. Take note that one side of the dice has a small lip to hold the bearing in place. Push a bearing through from the other side. 2. Drop a 4mm ball bearing into the channel as a weight. 3. Slide the other bearing onto the bar, pushing it over the retractable clips, which will hold it in place. 4. Slide the bar into the dice, securing all parts. I hope you enjoy printing and using this unique wooden rolling dice.
