*Important: Rubber-sponge gaskets for preventing sound leakage are ready. If you have ordered this item, please PM or email me with your order information and address. jcho@abitedesign.com.
I will send you a couple of gaskets via airmail.

The Minimized Gramophone "iAcoustic S" is an accessory for your iPhone, but it was not intended for an additional, separate device.
You need the charging cable for the iPhone every day, and the iAcoustic S was designed to transform the cable into a multi-functional device. The cable dressed up with the iAcoustic S can become an acoustic amplifier and a stand as well as a charger. When you put the cable into your bag, the iAcoustic S can also be a cable winder.

Its design was simplified for following the additional functions, and to provice the longer vibrating air column for the better and louder sound quality, its curved tube shape was created. The thickness of its bell and curved tube is 0.8mm.

It can also fit the iPhone with a typical case or a bumper. A mock-up plug is included, so you can use it instead of the charging cable when you don't need the cable.

* It works with the original charging cable.

A Merkaba, 9cm from tip to tip. (That's about 3 1/2", for us groundlings.)

Five intersecting tetrahedra with an icosahedron inside them.  There is just enough space between all the pieces that it will print as 6 separate objects.  The edge length of the tetrahedron is 7.5cm, it stands 8.6 cm high, about the size of a tennis ball.

There are six regular convex polytopes in 4D, which are analogous to the five Platonic solids in 3D. This is the sixth, the hypericosahedron, with 600 tetrahedral cells.

This was the hardest of this group to make a printable model of. For a Schlegel diagram one would need quite a large size to allow the amount of interior complexity required, and it gets difficult to build as well as expensive, so I used this face-first projection suggested by Henry Cohn. Some of the tetrahedral are collapsed and become planar, but on the plus side the complexity is on the outside where you can see it!

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 isn't one of the 4D "Platonic" solids, just a polytope that a friend of mine likes. It has icosahedral and tetrahedral cells.
