This tree-like surface was generated with a single mathematical expression using the implicit surfaces filter in MeshLab.
This model is solid. I also have two versions that have more "branches" and have been hollowed out. A small, thicker version called Implicit Tree Small, and a larger. thinner version called Implicit Tree 114mm.
This model is made of a two continuous bands that wrap diagonally around a torus shape 45 times before connecting to the original starting points. Here's two more Spiral Tori: Spiral Torus 110mm and a colored version Holiday Spiral Torus
This model is based on a snub truncated icosahedron; the hexagonal and pentagonal faces are deleted and the triangular faces have been extruded with a twisted stellation.
Here's my extra long 55-inch (approx.) necklace made of 120 octahedron links. Each link is a little under 5/8 inch by 3/8 inch (16mm x 9.5mm).
Also available:
The Octahedralink Necklace, a 36-inch necklace with 72 octahedron links.
The 7-Foot Necklace, a super-long, 7-foot necklace with 185 octahedron links.
And the Octahedron Link Necklace, a 30-inch necklace with 36 larger, chunkier, clunkier octahedron links.
This is your basic pea whistle, except that the "pea" is a plastic sphere. It is VERY shrill and VERY loud! Great for emergency situations, or if you just want to be annoying.
A larger version of this whistle pendant is available here.
Due to the small size, this whistle pendant may require extra cleaning before use.

A smaller, even more annoying, version of this whistle is available here.

This part consists of all five Platonic Solids nested one inside another.
From largest to smallest, there is an icosahedron (20 triangular faces), a dodecahedron (12 pentagonal faces), a hexahedron (6 square faces), a tetrahedron (4 triangular faces) and an octahedron (8 triangular faces).
The overall shape is a Rhombic Triacontrahedron, a combination of an icosahedron and dodecahedron). These can be nested infinitely following the same order.
This tree-like surface was generated with a single mathematical expression using the implicit surfaces filter in MeshLab, and a shell was added to the isosurface as well in MeshLab. A hole was added (subtracted?) at the bottom to reduce the overall volume.
I also have a larger version, slightly thinner in appearance, here: Implicit Tree 114mm.
