The Magic Shop offers a wide range of original dice, some geometrical jewelry and a few strange objects.

The dice are from different families like the Average Dice where you must sum the numbers appearing on the top face, the Truncated Sphere Dice, intersection of a polyhedron with a sphere and some other original creations.

The jewelry includes Double Marble Pendant, Dod Earrings and Dod Pendants, Reversible Bracelets as well as some unusual rings.
Finally, some objects are difficult to classify, for example the Hexbox, the Cup Holder or the MegaWireSphere.

Brunnian Pendant Stainless Steel
by Magic
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).

Brunnian Links
by Magic
These are 3 interlocked links. Brunnian means that even though the 3 ellipses are interlocked, no two of them are linked (in other words, remove just one ellipse and the two other ones will fall apart). They stand in 3 perpendicular plans and measure 3.5cm.
SUCCESSFULLY PRINTED.

Brunnian Circles
by Magic
The Brunnian Circles are made of 3 interlocked rings.
Brunnian means that even though the 3 circles are interlocked, no two of them are linked (in other words, remove just one of them and the two other ones will fall apart).

The red circle in on top of the blue one, the blue one on top of the green one and the paradox is that the green circle is on top of the red one.
This is possible because they are pseudo-circles: in reality they do not stand in a plane but are "waved".

Their diameter is 4cm and they thickness 5mm.

SUCCESSFULLY PRINTED.

Space Filling Polyhedra
by Magic
Space Filling Polyhedra
A regular dodecahedron and this other unusual polyhedron (that I call "Anti-Dodecahedron" but George W. Hart call it "Concave Dodecahdron") can fill the space (use the same proportion of each ones).
If you take into account their respective volumes, this means that dodecahdron alone can be close-packed with an efficiency ratio of more than 90.43% (which is not too bad, knowing that for spheres the maximum is supposed to be less than 74.05%).

This set contains only two ployhedra: one dodecaheron and one anti-dodecahedron.
Order it several times to fill the whole space... :)

Square Fabric
by Magic

Square Fabric

This is a fabric made of 84 links. 60 of them are identical squares. The 24 links on the borders are smaller so that there are not too loose.

Also have  look to a similar product by Stop4stuff.

Triacontahedron
by Magic
A large colored wireframe model that shows a Triacontahedron that includes a dodecahedron and an icosahedron.
It can be used to calculate the volume or the triacontahedron.
Using as only information that the diagonal of a pentagon whose side is a has a diagonal of size φa you can prove that the volume of the triacontaheron is 5/2.b.b.b where b is the large diagonal of the rhombus (the blue segment).
