tetrahedral lattice 3d models

I made an openSCAD program to generate a ball and stick model of diamond or silicon crystals. The model is printed in layers, with each ball having a space for the connector to slot into. They take quite a while to run (up to 10min per .stl) so...

A simple, two-part press-fit tetrahedral lattice structure.

This elaborate tetrahedral lattice has a high degree of symmetry, and shows an elegant crystalline uniformity when viewed from the proper angle. ...Video on...

It's a tetrahedral dreidel for Hanukkah. Although regular dreidels are more suspenseful, this version is straight to the point and I just like it better so I made it. With an edge length of 25mm, this model is indubitably a 3D one! ... Good...

A model for a tetrahedral molecular structure. ... The bond angles aren't 100% perfect (but fairly close) - we'll just pretend there's a lone pair somewhere ;)

... trusses. ...For these trusses all the tetrahedral edge lengths are equal. The hubs will work with edges of any length as long as they are all the same length. ...The hub holes are sized for 3/16" dowels along with enough room for a bit of glue.

This model is the dual of the Tetrahedral Intersected Parabolahedra model. This one has 248 faces of 22 types. ...This model was generated using Stella based on the original model which was generated by vZome.

Four overlapping symmetrical parabolahedra with their individual axes having tetrahedral symmetry. Their centers are on the vertices of the tetrahedron and the tetrahedron is inside of all four of the parabolahedra. Each parabolahedron is rendered in...

Students designed specific tetrahedral molecules (such as CH4) and printed them using the 3D printer. This is the model I created for instructional purposes. ... Instructions Here's a YouTube playlist...

Couldn't figure out whether I wanted to make a dodecahedral or tetrahedral puzzle, so this seemed like the obvious choice! It's a simple Face-Turning Dodecahedron (colloquially, a "megaminx") transformed into the shape of a tetrahedron. ...The...

This is an endcap for Henry Segerman's Tetrahedral racks model. It is designed to be glued onto the end of the models after assembly to keep them from coming apart. ...It may be possible to drill holes for pins/dowels as well but this model should be a...

These are corners you can use with common drinking straws to make tetrahedrals. Made these as game pieces for a game played with quadcopters, like the one shown. The stinger is used to pick up the tetras. ... Test video here:...

They can also be used to model tetrahedral numbers {1, 4, 10, 20, 35, 56, ..., n (n+1)(n+2)/6}. The spheres are intentionally welded with each other for easy use with students. The activities can be used at many K-12 levels, depending on the...

For advanced students, they could focus on the algebraic exploration and seek a function for the progression of triangular and tetrahedral numbers. Of course, art should be sought at all levels of math instruction. Lesson Plan and Activity...

Tetrahedral Spikey: Each side of the big triangle is about 86mm. A raft would be necessary for printing; support is not needed. Starting with an equilateral triangle, one can extrude at a tapering angle of -19.4712 degrees (arccos(1/3) -90 )...

This is a combination of pieces that can be fitted together to create a dimensionally accurate tetrahedral model. (109.5 degree angles) I designed this myself to help visualize the 3D structure. Simply drawing the lewis structures doesn't fully...

This partial lattice of Dimpled Rhombic Triacontahedra (hereafter DRT) consists of 4 outer DRTs translated with tetrahedral symmetry around the +1,+1,+1 vector toward the “dimples” of the original DRT. Other possible translation symmetries include...

This is a lattice cube I made inspired by makers muse's lattice. ...I would also like to point out that I printed it small, this means that when printed at full size it will be a lot higher quality.
