Cube with Tetrahedron inside 3d models

To use this model, print and assemble with instant glue, following the Sketchup images for guidance. Attach the hollow gear in the big hole, then the crank-gear part at a 45-degree angle. Use tweezers to press the parts into place and let the glue...

Geometry Specifications: Units: Centimeters Polygons: 27060 Vertices: 27066 Triangles: 0 Quads: 27060 Ngons: 0 No vertices with more than five edges. ... Model Information: Dimensions in centimeters: 13.9cm x 15.7cm x 12.6cm Dimensions in inches:...

Each of these bridges can be supported directly from the build plate, so there should not need to be any support material built above the part itself.Another advantage of the on-edge orientation is that it fits perfectly inside a cube. If you wanted...

I was messing around with tetrahedrons and decided to make a Ghostblood version there are 4 versions, enjoy

... tetrahedron, while "st_level-1.asm" features four such shapes (16 total). Levels 2 through 6 increase this count to 64, 256, 1024, and 4096 tetrahedrons respectively; however, level 7 was not attempted due to the computer's struggle with level 6.

-Scored thin cross hatching lines with hobby knife on faces of octahedron and on the bottom of each tetrahedron. -Used hot glue to attach a tetrahedron to each face of the octahedron. Initially tried used Zap-A-Gap CA+ brand glue with poor results. ...I...

Score thin cross-hatching lines on the faces of the octahedron and the bottom of each tetrahedron with a hobby knife before attaching another tetrahedron to each face of the octahedron with hot glue. Note that Zap-A-Gap CA+ brand glue may not work...

2D tools I used were smart decision and center line.3D tools I used were extrude base and made it draft outwards 29 degree

<p>This is a tetraedron that will be used as object to be moved by robots during robotics challenge.</p> <p>It is a more robust version of the tetraedron provided by ajw05001.</p> <p>This thing has been designed using onshape software. ...You can get...

This is an inverted pyramid - a 3-sided pyramid, to be precise. ...You can turn it right-side up, if that's what suits your fancy.

This is a robust tetraedron that will serve as the primary object to be manipulated by robots during the robotics challenge. It's an enhanced version of the original tetraedron provided by ajw05001, boasting improved stability and durability. The...

I used the polygon tool to make a triangle then used the extrude boss/base tool to make it into a tetrahedronMass = 22.56 gramsVolume = 3090.91 cubic millimetersSurface area = 1529.15 square millimeters

For 2D I used the rectangle and the line tool.For 3D I used the extrusion and extrude cut feature.

A Three-Dimensional Figure Composed of a Pyramid Base and Three Rectangular Faces Meeting at a Vertex.

Four sided figure.

I made this model using some feature tools such as extruded boss/base. ...Some sketch tools I used to make this was the polygon tool and the lines tool

For this model, using the sketch tool, a triangle was drawn onto the top plane. Then the drawing was made 3D using the extruded boss/base tool. Later, using the chamfer tool, the three edges in view when viewing the top plane were selected (make sure...

For amusement, a mere piece of metalwork is requested.

Tried to get only a four faced pyramid, but couldn't get it right.

A standard quadrilateral figure that ranks as one of five fundamental polyhedra in Platonic geometry, and simultaneously falls into the category of eight convex deltahedra.

Three-Dimensional Pyramid Shape Made Up of Four Triangle Sides.
