Bic Challenge now is only bic meal. When user donb ask if it's copyrighted I made a google search and find the din-ink owners, it is copyrighted as well.

Turn your pencils into a couple of stacked cooling towers, very cool(ing)
I got the idea from a suggestion by relet thingiverse.com/relet

This hanger was requested by a friend who is very environmentally conscious. I thought this was a great way to recycle 2 bottles while utilizing the TOM's capabilities! A design similar to this by Chinese designer Xuan Yu inspired this thing's creation.

One thing to note is that the holes to accept the threads to the bottles are not threaded. A compression fit seems to work well enough.

This thing is part of a final project for CPSC 183 Technology and the Law with Prof. Brad Rosen at Yale University. The idea of this project is to ask friends for ideas for physical objects that they would like to have that could be printed on the Makerbot TOM. I have designed them, printed them out and given them to the people who requested them. I also have uploaded them here to Thingiverse to add to the library of physical objects that people find cool, useful, or just plain fun!

Just a quick hack to have a physical model.

This is the better version of the one that I was going to make. First version had a tile for each number. For this version a slider is placed over the numbers to show the right numbers in that month.

The font I used this project is Daisy by Richard William Mueller

Craig thingiverse.com/builttospec cut the wood for me with his laser cutter.

It's very important to let others know the hazards of operating dangerous equipment, especially automated equipment, and especially when specialized safety equipment may be necessary. This warning label lets people know to be careful around your laser cutter, lest they be blinded by awesome.

Hand held air blaster, shoot bursts of air at all of your friends. Or put out candles.

Based on the following design quantumbalancing.com/images/goldenmeangauge.jpg

When searching for a design I also came across those, which look much nicer :

I present to you, the RepRap tie!

Update 12.30.2011: Added minecraft stl one one 20x20cm build plate and individual pieces in zip file. Yet untested! Don't know how well the holes will print when laying flat, please leave feedback if you try.

Update 12.30.2011: Added a stl file of a tie made from a stl file. Check out tie_stl.zip for source code. Not yet printed!

For years people have made ties out of wood, and I adopted the principle for 3d printing. Could it be a world first?

The basic idea is to take a 3d model, cut holes in it for string and then cut it into smaller pieces so the tie will bend.

I'm not overly satisfied with how the ties sits around the neck, perhaps someone has an idea for a better solution?

Also, any special ideas for a tie, just make a comment and I'll give it a go. :)

Inspired by some laser cut projects on Thingverse I made this crossbow for my son. It uses a rubber band and has the gun lock built into the handle. It will shoot a sucker dart across the kitchen and stick it to the microwave with a satisfying smack.

A hook that you can clip onto then end of a horizontal surface, such as a tabletop, bookshelf, etc. to hang things on.

I'm using it for hanging a basket with filament on. I'm using Vik's Y-bearing holder to make sure that it can rotate (see thingiverse.com/thing:921 ). I put a loop of rope through the two holes that hang over this tabletop clip.

Version 2.3 has some improvements, the hook's lowest point is now nearest to the table. A cord will tend to rest there causing minimum torque on the hook-clip.
It is made stronger at the two 90 angles that have to withstand forces. This is a more efficient use of material and builds faster.
A hole under the hook where no material is required for an adequate strength of the hook.

Version 2.3_thin is simply for a thinner tabletop/shelf.

I made some metabrick at the Providence Fab Lab. I scaled it for 1.6inch Delrin, so it didn't come out correctly, but it still snaps together.

This little cut-out stage has sides the same size as the build volume of the MakerBot. Printing it out will give you a little stand-up stage illustrating the volume a MakerBot will print in, along with a reference of the extrude thickness.

A more sophisticated version of this file, with more text and some known printable and known unprintable shapes would be a valuable tool to people trying to get a sense of the power of the tool.

some acrylic knuckles as a "paperweight"

i used some scrap acrylic aprox 0.333" i would suggest making the finger holes more oval, maybe even chamfering them

This is a 4-pin tumbler lock with a key and display case. Insert the key and turn clockwise to get a smiley face!

This is a remake of something that my Dad made when I was a kid. His version was made of wood. Its cool because it makes the belt look like it is defeating gravity!

I took oomlout's design and adapted it to my hardware.

I usually watch my iPod at night while I’m sitting in bed - the problem is having to hold the iPod out in front of my face. I thought that it would be nice to have some helping hands, so I designed some.

This is my design for a landscape iPod nano "hand" holder - hence the cheesy "i" prefix to the name.

I don't know why I didn't make this design available a long time ago, but I just remembered I was hanging onto it when I could have been sharing it.


The design is free of charge. You can use it on the proviso that you share a small part of your personal expertise in the education of others. You can do this in any way that you wish and your contribution need only be small. If you’re a busy person then you can always contribute to a charity like The Fred Hollows Foundation hollows.org

Today was Fashion Hacking day with Diana Eng at NYC Resistor and I've wanted to make these keyboard pants for a long time. The basic idea was to take a flexible silicone keyboard and somehow integrate it with some pants (or shorts). I had they keyboards laying around for a while and I ran down to the Conways to get some jeans for about $8 (Yay fulton mall!)

This was inspired by a cool project I saw a long time ago on the hypernets: engadget.com/2008/04/23/keyboard-infused-pants-make-it-okay-to-grab-your-crotch/

These were my design goals:

- Built entirely out of cardboard
- Does not need any glue (all the connectors snap into place)
- still mechanically stable

This is the 5th iteration of the design and finally it meets all these goals:)

This is a "radiolaria" sculpture roughly modeled on the drawings of Ernst Haeckel. It has simple icosahedral symmetry, with thirty "spines" radiating from the edges.

Use this to guide your cables with.

This is a simple two part compass for drawing circles, measuring, and navigating the open seas old timey pirate style.

Parts:
- 2 copies of the compass half
- 2 thumscrews
- 2 washers, 1 wingnut and bolt

This is a simple sliding case style tripod mount for the iPhone in response to the first remake challenge. All you need is one 1/4"x20 nut that press-fits into the bottom of the case. Many thanks to Daniel Johansson for providing this excellent iPhone 3G model: sketchup.google.com/3dwarehouse/details?mid=22f5cfad1fd21b26ca3028a0a5ef4401&prevstart=0

This is the design we used for the first batch of MakerBots. These are the lasercut design files you will need to make your own if you have access to a laser cutter.

An eight-legged big spider robot.

The design goal was to create a legged robot that is large enough to walk regular stairs and strong enough to lift simple loads. It also had to be simple enough to use regular RC-srevos and could be cut with my minimal CNC machine.

This is a set of plastic snap-together blocks that was designed for a prototype universal constructor. You can see a simulation of a robot made from the blocks here youtube.com/watch?v=LumLzSQE5Vw

You can get more info on the strengths and weaknesses of the actual physical plastic blocks here molecularassembler.com/KSRM/3.18.htm

This is a slot-together model of the first stellation of a dodecahedron. The slot sizes are appropriate for "172" illustration board, but you can scale the pieces to construct this model out of other materials.

This was to fulfill a need I had to control my iPhone earbuds. You can see all the revision here: eagleapex.com/de/owl-wrap/
And after showing it around, I put it on Esty and have sold a few.
The "O RLY?" is from my redrawing of Helvetica Neue UltraLight as single-line objects for vector etching.

Note: this doesn't fit the new Shuffle or iPhone 3GS earbuds with the 3 button remote. I'm working on an update.
