shortened top since printer didnt seem to like printing the top part when it was tiny

this one has a hole down the middle to put stuff in like a toothbrush~

A simply Mayan inspired pyramid to print and goo~
will add another pyramid that is the same but with a bigger top and empty inside for those who may wanna use it as a fancy container like item :D

Robot for develop3d contest.

Trying to print a pyramid vertically without getting the top vertex being a plastic mess is a challenge.

I have not found a pyramid resting on a side for a more easy printing, so here it is!
No more messy tops!!

The source is from "Small Calibration Pyramid" by LawrenceJohnston (http://www.thingiverse.com/thing:22340)

I have also added the equilateral version of the pyramid.

The 3D Tangram as envisioned by my grandfather William Perkins. This is an updated version of the original Featured thing 15754.


Takes the 7 piece tangram and extends it into the third dimension by making it a pyramid.
Can be used as a puzzle to recreate the pyramid, or new shapes can be made by reorganizing the 7 pieces.

The new Sphinx Holder conveniently holds the Pyramid upside down so that you can see the tangram shapes. The Holder also has some tangram puzzles on the side for you to match with your 3D Tangram. You can get some interesting landscapes with the 3D Tangram.

See en.wikipedia.org/wiki/Tangram for info on the Tangram.

Simple Wire Frame Pyramid

Simple wireframe triangle geometry.

This thing was made with Tinkercad. Edit it online tinkercad.com/things/dVxVHPi9W0U

A zelda object. Designed in Sketchup by Scott L., a grade 11 student.

Per Cymon's suggestion (comments, parent work), split each in half (was that the correct half to cut?) leaving four identical parts, not just two.

This is a simple calibration object designed to test accuracy of your x, y and z axis linear travel, angular alignment and slicing settings, with some small bridges thrown in.

As part of on-going collaboration with the Crawford School of Art and Design in the area of 3D printing we are producing parts to be used by, Dean O'Connor, a final year student in his work. Some pictures of the installed piece are included here.

In this case we are making flat triangular shapes to be used to construct a large geodesic dome as part of a piece on the un-realised promises of utopian architecture (or so is my engineering brain's understanding of the piece). The piece will be translucent enough to allow internal projection of colours or images to show through to the outside surface. As part of illustrating the theme of unrealised utopian dwellings the piece will attempt to show the imperfections of manufacture and assembly that appear as a result of its imperfect creation. So that means we need to actually ensure some of the features and flaws possible with 3d printing (such as curling, build platform surface texture, bits of torn kapton stuck in the first layer, residual colours from other prints, honeycomb pattern, gaps, printed surface texture) are included or even accentuated in these pieces... which is an interesting an unusual request!

The photographs of all the triangles prepared were all printed on the same machine with the same white plastic. The different colours and tones come from various sources including: black marks drawn on the filament to ensure the filament is being drawn into the extruder correctly, pieces of different colour plastic being left on or falling onto the build platform and being incorporated into the print, Kapton tape unintentionally incorporated into the build, white ABS glue used to patch over small tears in the build platform, acetone and white ABS putty used to repair damaged pieces.

A simple geodesic dome can be made with triangles joined edge to edge. In this case 10 equilateral triangles and 30 isosceles triangles. The isosceles triangles form 6 pentagonal pyramids. The equilateral triangles fill in the gaps. The dome will be about 30cm (1 foot) in diameter.

To make it transparent enough to allow the projection to show through to the other side the parts will have to be very thin. The original idea was to use totally flat triangles of 2 or 3 layers thickness which could be assembled like paper craft models. However, these tended to bend when being removed from the build platform, curled up at the corners, were difficult to assemble and were not very strong once assembled!

The design was modified to include the following features:
1. mouse-ears at apexes to prevent curling
2. a thick rim around the edges to provide a large bonding area for strength when assembled and resist bending when removed from build platform
3. angled edges to make for easier assembly, with the angle chosen to ensure the edges meet at the correct angle for assembling pentagons
4. a triangular cutout giving a thin central region to enhance transparency

Expected print time on a Thing-o-matic is about 20 minutes per piece or 13 hours in total! O_O;

Work in progress for my phone dock.

Ever felt the need to show off 84 very cheaply made marbles? Look no further. Simply fill up in a tetrahedron pattern, drop the thing by mistake, repeat a few times, then manage to do it correctly. Done :)

After reviewign my original design of a sphere inside a cube, I decided to make a pyramid inside a cube. Simple design, but I appreciated it.

My grandson and I were up early this morning and he wanted to make a storage box for some of his things. A Thingiverse search didn't turn up anything that interested him, but then he noticed the burn hazard warning sticker on the TOM and decided on a pyramid shaped box. The OpenSCAD script just took a couple of minutes and after a quick look through the filament bin for color ideas it was time to hit the print button.

I teach Linear Algebra to a small class of High School students. We took a few days to learn openSCAD and use the multmatrix function to explore some "real world applications".

The kids in the class had no prior programming experience and I think openSCAD was a great way for them to learn some of the basics of programming.

Their homework assignment was to design two objects, a building and a tree, by writing their own transformation modules using the multmatrix function (i.e. no using the built in rotate, translate, etc. functions, although union, difference, intersection were ok). Here are their buildings.

A threeway 60 degree pipe joint for 1/2 inch schedule 40 pvc pipe. 4 of these should make an Isosceles pyramid, or a PVC TeePee. I'm really hoping somebody takes this idea and makes it better. And other variants could produce scaffolding, or a really big tinkertoys set. Break out of the 90 and 45 degree rut the Hardware store imposes on you.

This puzzle is similar to the rubik's cube and is currently massed produced and can be purchased from the producer, Meffert's. However I wanted to design a smaller, flat faced version. It also has a different mechanism than the massed produced version. It should work perfectly in theory, though finding the right size screw might take some work. I could always add pins that you could just glue in place if anyone wants. I also split two of the parts in half because of overhang problems. This way it should be able to be printed without support material, and then the two halves would have to be glued together.

Unfortunately I don't really know how to orient the pieces, so hopefully you guys can do that yourselves.

With that being said I hope someone attempts to make this, and I am sorry ahead of time if it doesn't work


Edit 1) 4/21/11: Changed the instructions to make it more clear.

This is a model stand that I built to display the Tie Interceptor model (http://www.thingiverse.com/thing:5549) that I printed out. It uses the Global Dynamics Logo by Modelmaker and does some modification: resizing, rotation and copying to create an open pyramid where one can display a model.

The current version of the file only has a 3mm hole in the top so you can use any piece of filament that you want to adjust the height to.
