For a very nerdy Valentine's Day, I give you heart gears. This was inspired by Greg Frost's Broken Heart thingiverse.com/thing:4683, but it fits in the palm of your hand and can be twisted like some kind of worry ball. It makes use of the heart shape from thingiverse.com/thing:6190, the MCAD involute bevel gear script from thingiverse.com/thing:3575, and nophead's polyhole script for making properly dimensioned tap holes thingiverse.com/thing:6118.

UPDATE: If you lack a 3D printer, you can now buy these from CarryTheWhat at etsy.com/shop/CarryTheWhat.

I was daunted by the complexity of Greg's design, so this one is much simpler, having fewer gears, and a much simpler attachment design (simply thread the bolts into tight plastic holes). It also uses a smooth heart shape and is made for the hand instead of the desk.

this is a connector design for assembling a 2V geodesic dome structure. based off the wizardry of c60's original Dome Connector, we've improved the design by shaping the hexagonal connectors like hexagons, and the pentagonal ones like pentagons — making it much easier to visually differentiate between the two different connector types. additionally, we've added pairing notches above the 16° B-length struts on both connector shapes, to help accelerate assembly.

A fix for the Stackable box to correct one of the edge connector lengths.

This has been fixed in the original ( thanks Martijn ).

A quadrisection of a sphere into four identical parts with some novel attributes:

1. The parts have no overhangs.
2. The flat 'bottom' is completely concealed after assembly; there are no flat spots on the exterior of the sphere.
3. Exterior is made entirely of 'sidewalls' where the resolution of FDM really shines.

My test samples were built in transparent PVC on a Solido SD300 Pro, but my goal was to design a Makerbot-friendly shape. Based on feedback from friends, I've adjusted the contours so the pieces 'grab' onto each other after assembly.

this is a skull i modeled in sensable freeform then surfaced and exported to solidworks.

I always dreamed about a compact-yet-elegant joystick for playing quick games on my computer - tetris, Packman, Mario, etc'..

I've made this simple keyboard joystick -
print it on your 3d printer --> stick it on your keyboard --> Play!

Strømg Lump Leaks is a ceiling lamp designed by Lamp Lumps (LL).

The used technique is self supporting interlocking of pieces (without gluing, screwing or nailing) of 547 different pieces of polypropylene routed with a three-axis CNC.

The conception and materialization is mixed by using digital and analogue means.

The first name Strømg is the junction of the English term strong with the Danish surname Strøm. Strong, because it is a robust three-dimensional puzzle witch form is the result of small variations in each of the pieces. Strøm, because this work is an homage to Holger Strøm and his IQ Lamp.

The Lump Leaks surnames suggest, for instance, the leaking drops of water or the leaking of information. The abstraction of the concept results, morphologically, in a piece that is the materialisation of the metaball modeling technique that was widely used by pioneers of digital media in architecture in the 90’s.

This was for a final project for my 3D modeling class. I went with a Combo lock. It was done to show how a basic combo lock works. Total size is 4 inches wide. 3.5 front to back and 2.5 tall and is made of 10 parts.

I was going to do a Anniversary release of the files, but I am releasing it sooner because I get asked every once in a while about the .STL files or the Inventor.IPT files so here you go. Enjoy.

Have you ever wanted a Gothic Cathedral of your very own?

Are you intimidated by the centuries long construction schedule, and the punishing job requirements of being a European Bishop during the Dark Ages?

Then We Have a Thing For YOU!

The Gothic Cathedral Play Set!

A version of the Beco Block man with a few revised pieces for better posability and aesthetics. The 'ff' female-female connector piece has been revised to be slimmer, have a tighter fit, and be easier to attach and remove. The 'mfmf' torso piece has been redesigned to have the arms a bit higher up, too.

This is a makerbot-sized interlocking 2V/L2 icosahedron dome (reference: simplydifferently.org/Geodesic_Dome_Notes ). Might be useful if you're planning a moon colony or are building a really small radar set. Or print it in PLA and you have the shade for a nifty lamp. In any case, here it is.

Notes:
1) You'll need 30 of the A-A-B panels, 10 of the B-B-B panels, and 10 of the B-H panels.
2) This should be about 30cm in diameter and about 20cm high when assembled.
3) The panels should be error-proof, i.e. they should interlock only one way.

UPDATE:
I have added DXFs for anyone who wants to use a lasercutter.

Beco Blocks are 3d printable, snap together, ball and socket based building blocks.

Initially created as a prototype for another ball and socket based project, these blocks functioned so well I decided to make a number of variations to allow the creation of more complex objects.

Created at Robots and Dinosaurs, the Sydney, Australia hackerspace.

This free model comes with MeshLab, the open-source stl viewer and editor. I cleaned it up a bunch in Blender, then exported to stl and sliced it up with SkeinFox/Skeinforge. Gcode included below (high-res for printing all the fine details -- 0.25 mm/layer).

I've included the source Blender files and also the Blender render environment I used to make the marble pic.

The original model was scanned by the ISTI-CNR and was released under the CC-SA license. More details can be found at: vcg.isti.cnr.it/downloads/3dgallery/form_laurana.htm

Whether on a distant planet, a dystopian wasteland, or your own back yard, fortune can be yours with this 3D printable gold pan! Comes in in two sizes: 4in dia (mini), and 8in dia (medium), and with or without riffles. Can also double as a change dish or emergency dinner plate.

Notes:
1) These are fairly large, so a heated build platform might help prevent warping.
2) The outer overhang is 45 degrees, so it should print without support, but I haven\'t tested it.

If anyone produces any gold with these, please post pictures.

Here's my first attempt at 3-d modeling. The Banana slug is one of the most unusual creatures living in the Pacific Northwest (U.S.). Since my transplant here a decade ago, I am still amazed at how big they can get - up to 8 inches. I've made ceramic slugs and crocheted slugs, so a plastic one seemed like fun.

This is a spatial Bricard 6-Bar linkage that can be made from card stock, best sliced by a laser cutter like the Epilog Zing. ( en.wikipedia.org/wiki/Raoul_Bricard )

There are slogans on the faces. I originally designed this cardboard toy to advertise the Make Lab at our school arts festival called ArtRageous. I called it a mechanical donut, but my more artistic colleagues called it "Perpetual Motion"

Feel free to put in your own slogans!

Albertus Mus in the Discussion comments also pointed out earlier work related to these folding designs. Check out:

(1) IsoAxis ( ac-noumea.nc/maths/polyhedr/IsoAxis_.htm )

(2) Kaleidocycles ( kaleidocycles.de/ )

Even though there are lots of great gears on thingiverse, I couldn't resist the urge to model some too :)

The combinations of parameters are too many to upload an STL for each, so I just picked a few.

I also made a version for helical gears: thingiverse.com/thing:1339

A python script to generate OpenSCAD models to generate two parts of a box that screw together and snap fit if you find your way through the maze :)

The Klann Lego Spider is a LEGO compatible prototype of the Klann linkage (see mechanicalspider.com).

Video clips of the spider are available at:
youtube.com/watch?v=Bl_5wCbvxMU and

Update to v1.1 at:
tinyurl.com/y8lhcr3

The legs for the vehicle were milled from 3/8" plastic sheet stock. All the rest of the components are from LEGO Mindstorms (see tinyurl.com/6nj6w), which we use to introduce first year students to robotic concepts.

The project evolved somewhat during the build, as can be seen in the videos and pictures. The turning video shows a simple timed turn where the vehicle moves forward for five seconds, reverses the direction of the left legs for five seconds, then moves both sides forward again for five seconds. The forward motion video shows a skinny version of the vehicle that had to be widened when turning was added, since the skinny version simply fell over on its side instead of making a turn.

this is a VAWT I made at the local fablab(protospace)
according to the labmanager the twist in the blades removes the pulsating noise
the normal darieus makes.
it`s made in openscad but the code is a little messy.(apart from openscad I only wrote some hello world like things for python tutorial exercises)
