Modular Origami
Modular origami (also known as unit origami) is a category of models which are built from multiple sheets of paper, connected by means of folding. Individual sheets are folded into units which are usually all identical or very similar.
This page lists models of a single type. You might be interested in folding instructions instead.

Just like the pyramid, this is a shell with an empty inside.
Meshed Pyramid (8 levels high)
While it may not be obvious at first, this model has some features which make it strikingly similar to the business card table model. The table’s top is cons...
Life-Sized Chair
This model is the size of a real chair. Unfortunately, it can’t support enough weight to be sat in. The surface is not covered in additional, “paneling” unit...
Golden Ball (Snub Dodecahedron)
The model’s name is a reference to the Golden Sphere from Roadside Picnic.
Decorated Dodecahedron (Penultimate unit)
This model is made from 90 modules (modified variant for triangular faces). Each face of the dodecahedron is made from a 5-triangle group, where the triangul...
FIT (Five Intersecting Tetrahedra)
At only 30 modules, this model is still much more challenging than most models with several times that many units, but also a lot of fun to fold. See the lin...
Truncated Cube (PHiZZ)
Generally, PHiZZ units are always connected in such way that three modules meet at each vertex. However, one can connect just two modules at some points, thu...
Modified Buckyball (120 edges)
This is my experiment in modular origami made from two different types of units: 60 PHiZZ and 60 Penultimate units. These two kinds of modules are quite simi...
Jitterbug Icosidodecahedron
You can squeeze this model and transform it into an icosahedron, closing the empty space between units. This is called the jitterbug transformation.
Icosahedron (Penultimate units pointing out)
A small modification used in this model makes it possible to create polyhedra with triangular faces from Penultimate unit in a more convenient way than origi...
Decorated Icosidodecahedron
One of the larger models I have designed, this icosidodecahedron has pentagonal faces made up of small triangular pyramids and triangular faces replaced with...
Icosahedron (120° units pointing outside)
See also: icosahedron from same units but pointed inwards.
Icosahedron (120° units pointing inside)
See also: icosahedron from same units but pointed outwards.
Klein Bottle
This model was quite difficult to design, as the two sides of surfaces made with PHiZZ modules differ a lot (due to the presence of “bumps” where units join)...
Spiked Pentakisdodecahedron (Sonobe)
There is one spike placed over two adjacent faces of the pentakisdodecahedron in this model. I haven’t checked if the angles actually add up, so it might be ...
WXYZ
Model is also known as WXYZ Diamonds.
Tux, the Linux penguin
Tux the penguin is a mascot of the Linux operating system. The logo was created by Larry Ewing () using The GIMP.
Steinhaus Puzzle
This puzzle, described in Hugo Steinhaus’ book Kalejdoskop matematyczny (Mathematical Snapshots, literally Mathematical Kaleidoscope) consists of six pieces,...
Spiked Icosahedron (Trimodule)
Apart from this basic version, I also made a variant of this model which has additional “fins” on the icosahedron’s edges.
Spiked Icosahedron (Penultimate Unit)
One way of looking at this model is to see it as an icosahedron with a pyramid placed on each triangular face. Another is seeing it as a dodecahedron where e...
Spiked and Finned Icosahedron (Trimodule)
This model is similar to the spiked icosahedron, but apart from the spikes on all faces, the icosahedron also has “fins” placed on its edges.
Spiked Dodecahedron (orange)
See also the same design with different coloring.
Sierpiński Tetrahedron, level 3 (Trimodule)
This model uses 128 Trimodules, forming 64 2-unit tetrahedra, and 126 links that connect them, for a total of 254 units. The links were made from narrow rec...
Möbius Strip II (Trimodule)
This is one of the rather few modular origami designs which use an odd number of units. Compare also with another similar model.
Möbius Strip I (Trimodule)
This is one of the rather few modular origami designs which require an odd number of modules. Compare also with another similar model.
Menger Sponge, level 1½ (Penultimate unit)
Thanks to the modules’ shape and the holes created in the spaces between them, this model looks almost like a level 2 Menger sponge even though it is actuall...
Large Icosahedron
This icosahedron has nine triangular pyramids pointing inwards on each face. The same shape can also be described as a truncated icosahedron whose each face ...
Koch Snowflake, level 2 (Trimodule)
Compare also with level-1 version of the same fractal.
Koch Snowflake, level 1 (Trimodule)
A level-1 Koch snowflake is just a simple hexagonal star, and this is the way of connecting the Trimodule units originally suggested in Nick Robinson’s instr...
3D Koch Snowflake (Trimodule)
This fractal is an analogue of the standard Koch snowflake. Level 0 is a tetrahedron. In each iteration, a tetrahedron with half the edge length is placed in...
Blintz Icosidodecahedron
There are six intersecting planar surfaces, each in the shape of pentagonal star, in this model. This leads to the most popular coloring with six different c...
