Dice & Marble - Solid, Split (tabbed or magnetic)

Why another dice  model…there are literally hundreds!

I recently created a marble model for my marble tower, in case anyone needed marbles. Well, as it turns out spheres don't print too well. So I decided to create a split sphere, with tabs, so two halves could snap together and form an imperfect sphere.

I also touted that the marble tower could be used for dice, but didn't really have any to test it with. So I decided to try applying the tab mechanism to the dice. It seemed to work ok, and since they're split, it saves a bit of filament because there were fewer layers and less color changes to flush and purge.

What's included:

There are three versions of the dice, and two versions of the marble:

• Profile 1: Solid Dice
  1. D4
  2. D6
  3. D8
  4. D10
  5. D12
  6. D20
  7. D00
• Profile 2: Split Dice with Tabs
  1. D4 - Solid (not enough volume to embed the tab)
  2. D6
  3. D8
  4. D10
  5. D12
  6. D20
  7. D00
  8. Marble
• Profile 3: Split Dice with magnets 
  1. D4 - Split (enough volume to contain the magnets)
  2. D6
  3. D8
  4. D10
  5. D12
  6. D20
  7. D00
  8. Marble

These dice have not been tested for precision, so I make no guarantees that they are fair and balanced dice. On the other hand, they have not been purposefully weighted to achieve a particular outcome.

For the tabbed version, see the gif for a demonstration on how to unfold the tabs and assemble the marble or dice.

For the magnetic version, each dice half contains channels for three 6x2mm round magnets. There's a pause in the print profile for installation. When adding the magnets, place 3 magnets in one half of the die, face-down in one direction (positive or north), and in the other half, face-up in the other direction (negative or south). That way, they'll attract. If you put them all in the same direction the two halves will repel. The magnets will most likely not be labeled, so to avoid confusion, take a stack of magnets, press three into one half from the same side of the stack, then press three into the other half from the other side of the stack.
