D18 Sphere

This is a Truncated Sphere D18.

The numbering has been done very carefully. Of course, numbers on opposite faces sum to 19. This leads to the fact that the 8 numbers around any of the 3 diameters sum to 76. But the dificulty has been the have the 6 numbers surrounding a spherical zone to sum to 57. It works for all the 8 zones (for instance, in the rendering - the brown one - you can see: 18 + 3 + 13 +11 + 7 + 5 = 57).

See this thread for more informations.

D4 Shell

It's a Truncated Sphere D4 without faces!
The idea of keeping only the round part of a truncated sphere die when the numbers are located on vertices or edges is from Clsn (check his D9 for instance).
The thickness is 2 mm. Since it does not contain a lot of material, this die is quite affordable.

All the D4: 
  - Truncated Sphere D4
 - Concave D4
 - D4 Shell

See also the D8 Shell.

Truncated Sphere D11 with 3-fold symmetry.

This die is inspired by the repulsion force polyhedra. Nonetheless, the underlying polyhedron (not rounded) is very different from the shape that can be obtained through this technique with 11 points repulsing each others.

Actually, I calculated the positions of 11 points to have a maximal radius for the circles resulting from the intersection of this underlying polyhedron with a sphere with the following constraints:
- 2 poles (upper and lower face - parallel to the horizontal plane)
- 3 points around each pole
- 3 remaining points corresponding to 3 faces perpendicular to the horizontal plane

The result is a truncated sphere with 11 circular faces of same radius.

It is numbered from 1 to 11: 2 numbers are on faces (poles), 6 between vertices and face and  3 on edges. The sum of the numbers on the 3 upper vertices surronding the North pole is 18.  Same thing for the sum of the 3 numbers on the lower vertices surronding the South pole and the sum of the 3 numbers on the edges of the equator.

This die is made of a shell of 1.5mm that contains support material to make it heavier. The engraved numbers have a 0.75 mm depth. They are quite big since they overlap the surrounding faces and thus should be very easy to read.

The Hollow Marble is a 7/8" (22 mm) hollow sphere with 2 holes at the poles.
Thickness is 3 mm.

Read this post for more information.

A 7/8 (22 mm) sphere with the altitudes proportional to those of Earth (from 0 to 1 mm). Only the Full Color Sandstone will have colors... Please also consider this new model.

The Ring'n'Roll is made of two portions of spheres, one inside the other. The outer ring can turn freely around the inner one.
The internal diameter is 20 mm (ask me if you need other dimensions). The inner ring can turn inside the outer shell (the clearance between the ring is 0.75mm, the thickness of each ring is 2 mm)

SUCESSFULLY PRINTED in Alumide. Unfortunatelly Metal is not possible (movable parts). A version with holes (less expensive) is also available.

Very very addictive...

Double D6

This is a compound of a nearly regular D6 and of a sum-D6. As the sum-D6 that composes the shell gives results from 0 to 5, the core is numbered from 2 to 7.
As a consequence, when you roll this double die, you got the same results as summing the results of two regular D6. But in a very original way!
For instance, in the rendering, the upper face of the core show 3 pips and the upper part of the shell, around this face, shows 2 extra pips. Thus, the result is 3+1+1 that is 5.

SUCESSFULLY PRINTED in White Strong and Flexible.
Not printable in Metal, sorry (movable parts).

Dice Template
These are the 5 platonic solids to be used as dice template.

You can download them freely and modify them.
If you want to order this set of platonic solids as they are, there is no markup: you just pay for the material (as usual, shipping is free for any order of $25 or more).

In order to reduce the cost, they are hollow, with a tunnel joining the internal shell to the external shell. This tunnel is meant to prevent the automatic repair tool of Shapeways from removing the internal shell. But it is small enough to be invisible and to keep the support material inside.
The thickness of the models is 1.5 mm which is thick enough for Strong and Flexible materials, Details materials and Alumide.

A Youtube tutorial on how to hollow a die is also available.

Truncated Sphere D15.

This die is inspired by the repulsive force polyhedra although in this case, the underlying polyhedron (not rounded) is very different from the shape that can be obtained through this technique with 15 points repulsing each others.
Actually, I calculated the positions of points (5 at each tropic, 5 at equator, none at the pole) to have a maximal radius for the circles resulting from the intersection of this underlying polyhedron with a sphere. The result is a truncated sphere with 15 circular faces of same radius.

It is numbered from 1 to 15: all numbers are on edges.
The sum of the numbers on each tropic is 40 and the same applies to the equator.
Except for 8, all the numbers go by pair summing to 16: on the tropic two numbers symmetric relatively to the plane of the equator sum to16 and on the equator circle itself two numbers symmetric relatively to number 8 sum to 16. 

This die is made of a shell of 1.5 mm that contains support material to make it heavier. The engraved numbers have a 0.75 mm depth.

Truncated Sphere D32, regular edition.
Based on an idea from Orangery.

The underlying polyhedron is a non-uniform icosidodecahedron (a kind of polyhedral soccer ball).

The distance between two faces is 30mm. The thickness is 1.5mm but it is full of support material to keep it heavy.

It is numbered from 1 to 32 with the difference between two numbers on opposite faces being always 16.
If you take the sum of a face surrounded by 5 neighbours (there are twelve of them, that corespond to pentagons on the underlying polyhedron i.e. before the intersection with a sphere) and its 5 surrounding faces you will always obtain 99.

Sphere Dice Set

The Sphere Dice are solid dice obtained by intersecting a regular polyhedron and a sphere.
They are "as fair as possible": the shape is fair but, as the numbering remove some material, there could be a little bias (but probably not more than commercial dice).
Here you have all the 7 Sphere Dice in one set:
 - D4 Sphere
 - D6 Sphere
 - D8 Sphere
 - D10 Sphere
 - D% Sphere
 - D12 Sphere
 - D20 Sphere
For dice collectors and RPG players.

Get all the dice from D3 to D20 plus the D% and D24 by gathering:
- the Sphere Dice Set
- the DCC Expansion Pack
- the Odd Spherical Dice Set
- the D18

You may also be interested into the brand new D22.

The Happy Event Bead is similar the the Hollow Marble.
The difference is that it has slightly bigger holes (3 mm instead of 2.5) and these holes are not centered, so that the bead always shows the same side: this marble is intended to be used as a bead on a necklace without any holder (just insert the necklace into one hole and make it exit from the other one).
In this way, you can make a necklace with one bead for each significant event of your life (your own birth, your graduation, your wedding, etc. but it is mainly intended for the birth of your children).

Read this message for more information.

Suggestion for the Mother Day: offer to your wife a bead with the picture of your children on one side and a text saying "Happy Mother Day 2011" on the other side!

Necklace not included.

Alt D22 Sphere

This is an alternative Truncated Sphere D22. It has the same symmetries as the tetrahedron.
See the D22 with 5-fold symmetry for numbers located on the faces.

This die is inspired by the repulsion force polyhedra. In fact, the underlying polyhedron (not rounded) looks like the shape that can be obtained through this technique with 22 points repulsing each others.
But in this case, I calculated the positions of those points to have a maximal radius for the circles resulting from the intersection of this underlying polyhedron with a sphere. The result is a truncated sphere with 22 circular faces of same radius.

It's a small coffee cup whose handle is a moebius strip.
It is only attached on one side (where it is horizontal): I guess such a shape should be difficult to do without 3D-printing.
Oddly enough, it is quite ergonomic: put your thumb on the vertical part of the moebius strip, put the opposite horizontal part between your index and your medium, et voilà!

Truncated Sphere D14 based on a cuboctahedron.
Numbered from 1 to 14.

A D14 numbered from 1 to 7 twice is also available.

This a new version with a better engraving and a new orientation that should give better results.

Truncated Sphere D17 with a 5-fold symmetry

This die is inspired by the repulsion force polyhedra. In fact, the underlying polyhedron (not rounded) is very similar to the shape that can be obtained through this technique with 17 points repulsing each others.

Actually, I calculated the positions of 17 points to have a maximal radius for the circles resulting from the intersection of this underlying polyhedron with a sphere with the following constraints:
- 1 point per pole (upper and lower face - parallel to the horizontal plane)
- 5 points around each pole
- 5 remaining points corresponding to 5 faces perpendicular to the horizontal plane

The result is a truncated sphere with 17 circular faces of same radius.

For the numbering, as usual:
 - the sum of the 5 numbers of the two tropics and of the equator is constant (and equals to 51)
 - the sum of the 2 poles, of two numbers of the tropics that are symmetric relatively to the equator, of two numbers of the equator that are symmetric relatively to number 9 is constant (and equals to 18)

Truncated Sphere D9.

This is my own interpretation of the D9. Please check also clsn's version.

This die is inspired by the repulsion force polyhedra. In fact, the underlying polyhedron (not rounded) looks like the shape that can be obtained through this technique with 9 points repulsing each others.
But in this case, I calculated the positions of those points to have a maximal radius for the circles resulting from the intersection of this underlying polyhedron with a sphere. The result is a truncated sphere with 9 circular faces of same radius.
It is numbered from 1 to 9: 6 numbers are on vertices, 3 on edges, none on the faces. The sum of the numbers on the upper vertices is 15. Same thing for the sum of the 3 numbers on the lower vertices and the sum of the 3 numbers on the edges. This numbering is closely linked to the well known 3x3 magic square.

This die is made of a shell of 1.5mm that contains support material to make it heavier. The engraved numbers have a 0.75 mm depth. This new version has big numbers that should be easy to read.

Truncated Sphere D33 Frosted Edition

This is the Frosted Edition of the 33-sided die specially designed to be the 33333rd entry of Kevin Cook's dice collection.
This die has a diameter of 20 mm and a wall thickness of 1 mm only.
It should contain the white wax used as support material.

The numbering has been carefully studied.
All numbers are by groups of 3 that sum to 51:
 - the 3 numbers at the North and South pole
 - the 9 numbers at the equator and at the 2 tropic taken 3 by 3 (any 3 numbers at 120°)
All numbers sum to 34 by group of 2 (except obviously 17, since only 17 itself can sum to 17 to give 34):
 - all the numbers of the poles and of the tropics with their symmetric number relatively to the equator
 - all the numbers of the equator (except 17) with their symmetic number relatively at number 17
 

The Brunnian Pendant is a small version of the Brunnian Circles initially intended to be printed in Stainless Steel as a pendant. Unfortunately moving parts are no more allowed in Metal.

The diameter of the threads is 2 mm. The clearance between the rings is 1 mm.
Note that when hanged, the rings are a bit loose because of the necessary clearance (see the picture).

A cube of one cubic centimeter.
Can be useful as a sample, to compare the different materials (density, color, surface aspect...).
