POLYHEDRON RING / ANILLO DE POLIEDROS

Um die Verwendung von polyhedron() in solchen Fällen zu vereinfachen, habe ich die Funktion roundbox_v() entwickelt, die die beiden Vektoren für den Aufruf von polyhedron() errechnet und zur weiteren Verarbeitung zurückgibt. Primär bietet sich der...

using polyhedron to make Lego Specials

Here's a table: name of the polyhedron ---- filename ----- vertexa (how many you need to print) tetrahedron (4 faces) ---- tetrahedron_joint_big v1.stl ----- 4 hexahedron (6 faces, a cube) ---- hexahedoron_joint v3.stl ----- 8 octahedron (8 faces,...

Easy snap together almost any polyhedron created of regular polygons is made possible by the design of the hinge, which allows it to easily snap together and pull apart. The larger polyhedrons are quite sturdy and can be played with without falling...

The 'caps' on the top and sides of the sections represent concrete abutments that would reinforce the wall and they are 2 feet wide. The blocks in the wall are scale 1 foot X 2 foot. I tried smaller but they didn't look right but might work on that...

As one examines the polyhedron closely, it becomes evident that each face is an equilateral triangle, with all sides equal in length and each internal angle measuring precisely 60 degrees. The symmetry and balance inherent in this design make it a...

The 4-speed iteration of my 5-speed D20 shift knob takes center stage, boasting a design similar yet distinct from its 5-speed counterpart. ...Note that the bottom still features a centrally positioned pilot hole, though the mounting process itself...

Had trouble finding a plain icosahedron for my kid, so I made one. He wanted to paint his own dice for his friends and wanted it to be blank. Have fun! ... Update 9/23/23 - Made it exactly 20mm

A d20 for all your tabletop rolling needs!  The file comes with both a pre-supported model and one without supports.  The font on the dice is New Rocker, an open-source font that anyone can use. 

The human element is what truly sets us apart from the machines that surround us. It's a reminder that we are more than just code and circuitry - we're alive, and our presence makes all the difference in this world of ones and zeros. From the way we...

I deliberately divided this intricate D20 in two lengthwise in order to secure a crisp print; I then carefully printed each half, painstakingly sanded off warps, applied a thin layer of CA, and firmly pressed them together for a solid bond. ...Perhaps...

Create Your Own Magic 8-Ball Die Without Breaking a Sweat! Currently, I have marked this as a customizer-friendly project, but unfortunately, Customizer can't handle the complex array used to store the text. So, if you want to make changes, and...

this is a gift requested by my sister

I am working on designing an innovative icosahedron shift knob for a five-speed manual transmission. To ensure universal appeal, the base of this design is kept plain with only a centered pilot hole to make mounting adaptable across different models....

With home 3D printing, fixing a broken LEGO piece is easy and quick; in just 30 minutes you can have a new one ready for your child. We've successfully printed four pieces in mere four minutes using our RepRap printer. For optimal results, use 0.2 mm...

My sister has asked me to present her with this extraordinary offering.

A space-filling polyhedron, known as a plesiohedron in some cases, is a polyhedron that can be used to create an infinite pattern of identical polyhedrons by pairing them together. These paired polyhedrons fully fill space without leaving any gaps...

The Goldberg polyhedron, specifically denoted as G(3,3), is a three-dimensional geometric structure characterized by its vertex configuration of six equilateral triangles.

This polyhedron has been described by Jean-Pierre Sydler in his proof of Sydler's Theorem, which relates to Hilbert's third problem and states that every polyhedron is determined by its volume and Dehn invariant up to scissors congruence. ...Sydler,...

This snap-together set of polyhedron facets fell flat due to a critical mathematical miscalculation that rendered several key components incompatible.

Here is the second polyhedron that Petrie presented to Coxeter in 1926, accessible at https://www.thingiverse.com/thing:2884052 - This polyhedron consists of hexagons. The vertices of four hexagons converge at a point; this pattern is repeated in...

This toroidal polyhedron creates a remarkably symmetrical interior space; five chambers perfect for an Egyptian pharaoh's burial are neatly arranged within its structure. Each chamber has direct access to all other chambers via a triangular door,...

By pairing these two distinct polyhedrons together, it becomes possible to generate an infinite pattern of identical polyhedron pairs that completely fills every available space without leaving any gaps or voids in between. To learn more about this...

... the ideas of tetrahedral symmetry and a low poly/fast OpenSCAD implementation. Third attempt following OpenSCAD speed optimisation to it's ultimate conclusion - a single polyhedron. Not sure how I feel about that... ... More information and Proof

The most simple form to use it is this: v = screw_extrude_v(P, r, p, d, sr, er, fn, rf); polyhedron(v[0], v[1], convexity = v[2]); for a thread with constant diameter or v = screw_extrude_v(P, r1, r2, p, d, sr, er, fn, rf); polyhedron(v[0], v[1],...

This is another polyhedron design specifically tailored for the DJI OSMO ACTION camera. The 18-track mount covers angles from 18 to 40 and 45 degrees, ensuring seamless compatibility with the OSMO ACTION. Printing this model requires minimal...

Stewart's groundbreaking discovery, known as the G3 polyhedron, boasts faces made up of regular polygons all sharing the same edge length. This remarkable shape features 3 pentagonal faces, 3 square faces, and a staggering 7 triangular faces. The...
