... 3. Velcro or glue a tetrahedron to the oloid base. Make sure the two hinges are orthogonal to the two circles, respectively. (Refer to figures). Play, think, ask questions, and pass them on. Have fun! ####References 1. Bu, L. Bu, L.

This design features two intersecting tetrahedrons in the solved state. You will need to supply your own core and screws or springs from another cube. I recommend using a YJ Guanlong core, as these can be found for $3-4 and this has been designed...

Among all the various solids, exactly five can claim this esteemed distinction: the tetrahedron with its four triangular facets; the cube with six square ones; the octahedron boasting eight triangles; the dodecahedron displaying twelve pentagonal...

Lastly, the two-part tetrahedron, although identical pieces, is the most challenging - taking up to 30 minutes to solve. These puzzles can be 3D printed with a slight setback for imperfections, and sanding may be required for rough patches. The...

My OpenScad library aims to offer more versatility by including different base forms like octahedron and tetrahedron, as well as elliptical shapes and triacons. Eventually, the library will support free-form constructions too. To use my library,...

The library now contains 'platonic.scad' file with functions representing the five Platonic solids: tetrahedron, octahedron, hexahedron, dodecahedron, and icosahedron. These solids can be rendered using display_polyhedron() by setting their radius...

The list of shapes includes: Cone Cube Diamond (Octahedron) Dodecahedron Egg Horn Oval Pedestal Pentagon Prism Pyramid Soccerball (Icosahedron) Sphere Torus Trapezoid Triangle (Tetrahedron) Tube (Cylinder) Print Settings: Printer Brand: MakerBot...

Human: Sierpinski's Tetrahedron calculated using OpenSCAD. Update Nov. 12, 2015 - Original parameters are outdated, now adjusted for a fractal level of five with thickness at point contact set to 0.5mm. Printer Settings Printer: Da Vinci 2.0 Duo...

Joining surfaces adjacent to the obtuse angle will create the vertex of a tetrahedron, while joining surfaces adjacent to the same angle will also create the vertex of an octahedron. For maximum strength, print solid with adequate infill. However,...

It gets interesting when you combine multiple of these to make something called solids that also match certain key traits: the shapes must fit exactly together on all sides and form a consistent number at every one single vertex, which then gives...

As an added bonus, try finding a way to interlock four puzzle pieces into a truncated tetrahedron. This assembly can be placed inside the box. ...Known as "Blossom," this puzzle was invented by Bernhard Weizorke and requires the 50 micron offset pieces...

Only a few of the platonic shapes emerge (tetrahedron, cube, dodecahedron) but not the octahedron. No Archemedian solids emerge although the 32 face figure is close to a truncated icosahedron (soccer ball). as the number of faces goes up, the...

Tetrahedrons possess four three-fold rotation axes through their vertices; these are mapped onto the sphere while centering 3-fold patterns at the corresponding vertices. The Sierpinski triangles' pattern (sierpinski_triangles_3.dxf) is utilized in...

A versatile dice, shaped like a tetrahedron, with interchangeable corner pieces that snap-fit into place. Use it as a standard four-sided dice or let the unpredictable What-The-Hedron decide on your next action. You can even display one as a...

Unlike cheap printable or commercial ones, those have all you want :tetrahedron scalable shape for best stabilitysecure it in in place with screwsstar shape (not pyramidal) to prevent over-spray bouncingheavy duty shape to hold both heavy and light...

Assembling this geometric marvel requires 60 each of specific triangles and connectors, forming 12 pentagons and 20 tetrahedrons initially. The most obtuse connector unites these structures. Attention must be given to orienting fat triangles...

... was designed by Wolfgang Maas. To come: * Tetrahedron from Franz Sykora * Cube from Robert Byrnes * Cube from Paul Schatz * Cube from Wolfgang Maas * Octahedron from Robert Byrnes * Dodecahedron from Robert Byrnes * Dodecahedron from Immo Sykora

The original solving time is estimated to range from "one hour to a year, or more." The final shape forms a tetrahedron with five balls along an edge. A total of nine pieces and thirty-five balls are involved in this puzzle. There is only one...

The library contains shape primitives, hexagrams, equilateral triangles (prisms), 3-sided pyramids, tetrahedrons, 4-sided pyramids, tubes with adjustable wall thicknesses, slots with square or round ends, teardrops, dovetail pins and slots for...

Pieces in STL format: Tetryons (tetrahedrons): * neg_tet.stl - Negative tetryon, all four sides have negative polarity, modeled as holes. * pos_tet.stl - Positive tetryon, all four sides have positive polarity, modeled as connector tabs. *...

For tetrahedron (d4), cube (d6) or dodecahedron (d12) use "hub 3" for the axes, while for octahedron (d8) use "hub 4". ...I didn't create a "hub 5" which would be needed for icosahedron / d20, but I included the FreeCAD file in case you want to try...

After seeing a multitude of cube-shaped coin traps on Thingiverse, I decided to create some based on the five Platonic Solids: tetrahedron (4 sides), cube (6 sides), octahedron (8 sides), dodecahedron (12 sides), and icosahedron (20 sides). When I...

... Two-part tetrahedron: The most challenging puzzle, despite having only two identical pieces, requires no force to assemble. ...It may take more than 30 minutes to solve, but the process encourages creative thinking and problem-solving strategies.

These parameters are the ribCount; set to 3 for tetrahedron, octahedron, and icosahedron, 4 for cube, and 5 for dodecahedron. The other parameter is the dihedral angle, which is half the angle between two adjacent faces. Although this parameter may...

A Custom Guitar Pick Inspired by the Merkaba Pyramid, a Star Tetrahedron Formed from Two Triangular Pyramids Pointing Up and Down. The merkaba is an eight-pointed star made three-dimensionally. The pick itself takes one to three minutes to print,...

It's easier to think of it as four hexagonal faces of a truncated tetrahedron with the triangular faces removed. Here are two models that show how this pattern works. Six_hexagons.stl is made up of three truncated tetrahedra taken from an infinite...

The drone's shape can be varied – cube, ball, tetrahedron, icosahedron, dodecahedron. The clutch doesn't always need to be tightly connected; adjustable slip is possible. ...This series will continue exploring small land drones and their capabilities.

... points on the vase's surface can be adjusted to create star-like shapes. Tetrahedral faces allow users to transform triangles into tetrahedrons, with positive values creating outward-facing points and negative values creating inward-facing points.

The dihedral angle of a regular tetrahedron is approximately 70.53 degrees, while that of a regular icosahedron measures about 138.19 degrees. Notably, the former is roughly half the value of the latter, which explains why their models were so...

A bonus puzzle is to discover how to interlock four pieces into a truncated tetrahedron shape. This assembly can be placed inside the box. ...Known as "Blossom," this puzzle was invented by Bernhard Weizorke and works best with 50 micron offset pieces.
