The Automatic Affirmation Device only has one thing to say:
YES.
Will today be a good day? Will I pass that exam? Is this the best idea I ever had ever?
YES.
The Automatic Affirmation Device is your own personal confidence booster that is never wrong.

This is designed to be a gift, the perfect gift, (for you to give) to someone who is in need of some caring reassurance.

This is just an experiment I made with my iPhone 4 to make a 3D scan of a remote object and then to make a 3D model. Now I am trying to figure out what to do with the 3D model. How to integrate it into something to make a useful thing? It's a big mesh so I guess only 3D printing will work.

Just a Portal Sentry Turret made in OpenSCAD. The design is still lacking the legs, but ill add them soon. Enjoy!

A basic woman made as a test using MakeHuman. makehuman.org/

I made this in an effort to explore printing the human form on my printer and to learn how to use MakeHuman.

The .obj file has the whole body while the .stl files are just torsos.

If you look at the .obj file it has jaw bones, teeth, eyes, and extra "joints" (little closed polyhedrons floating inside). I believe I removed all of those extra bits in the "***test2.stl" although they did not cause me problems when printing the "***test1.stl"

One of our first "human" reconstructions made digital using hypr3d.com 's image-based 3D reconstruction.

This is a project i did for my Open thesis Fabrication, program in the Institute of advanced architecture of Catalyna, in Barcelona, Spain. It is a wind-turbine, that can be solely 3D printed in a RepRap machine, in order to provide people with free harvested energy. The project is still under way so i would appreciate anyone that would be welcome to try to make it, and let me know his ideas. I would also appreciate some help on the electronic part of the project.

This is a bust version of the figurine that's available from here shapeways.com/model/164604/ (this link has more pretty pictures too). You can also get this version at shapeways.com/model/191205/.
It's about 9cm high.

Polyhedron components with symmetric(unsigned) hinges. Also, now with octagon.

The previous kit thingiverse.com/thing:4934 had larger facets and signed snaps, and assembly was a puzzle. This script resolves these problems by using only one symmetric hinge. I adapted a concept from thingiverse.com/twotimes to design these hinges.

These parts are snap and dimensionally compatible with other things tagged "Elements". They are also useful starting blanks for building up more Element-compatible things.

If you noticed that this is a duplicate of the "circular elements" thing, you're right. I posted renderings separately for those who don't want to invoke OpenSCAD scripts.

3.2.2011 UPDATE. Added thin top truss parts for easier assembly.

This is a modular kit of parts to create a truss bridge. The sample shown has two center sections. The bridge can be made longer by adding more center sections and more piers if needed.

The parts list is shown for a two center section bridge.

file: assembly_110227h.skp shows the assembled orientation of the bridge.

file: bridge_4_110302.skp presents the parts in the printed orientation.

This is a complete two-leg walking mechanism of Theo Jansen.

To build a complete walking Robot, you'll need this Thing 4 Times and some Construction for the two Motors and Control of them.

OpenScad file allows you to specify size and number of blades. The example stl is a 5-blade fan.

This is a pocket watch housing for the highly programmable Makerbot Watch. ( wiki.makerbot.com/makerbot-watch ) Designed to protect the circuit board when not in use, while being able to hinge open for easy tinkering.

Inspired by the feedstock hinge ( thingiverse.com/thing:1358 ) , I tried to use the least amount of hardware as possible. The ABS filament acts as the hinge pin, and the clamshell parts have built-in bumpers that keep all the components well constrained. Adding 3mm magnets will really give the whole thing a robust feel.

There are two versions posted:

1. watch top.stl, watch bottom.stl; -These are pictured and have a more finished looking aesthetic, and more refined bumpers.
2. (rev4).stl; -These are an ultra light weight ribbed version that have a consistent material thickness, however requires a well tuned 3d printer.

For anyone who wants to make something similar, there is a dxf quantifying(1:1) the critical features of the parts.

This is an alternative extruder hot-end design for the makerbot, though it may work for other 3d printers as well.

The big advantage is that it does not require an insulator (usually PTFE or PEEK), which causes problems for some (or perhaps many). Instead, a stack of washers and nuts is used as a heatsink to reduce the temperature.

It worked really, really well for me, no more stalled extruders, stuck filaments, half-way prints. It heats up rapidly less than 1 minute from 25 to 220 degC), and I haven't had any problems with it (yet..).
I've only printed ABS so far, so I have no idea if it will work with other materials.

My original version used an aluminum heatsink (bottom image), but I thought that might be a bit hard for others to duplicate, so I built this one. Works just as well, just looks a little less fancy.

You'll need a small fan, stainless steel M6 bolt as well as a stack of M6 nuts and 25mm M6 fender washers in addition to asome components from a standard makerbot extruder.

Something fun.

Mesh ball created in TopMod, imported into blender.
It bounces off a concrete floor... not sure how long for though :)

Would make a great cat toy too.

What's cooler than transformers? A Cupcake CNC transformer with a Bre head? This is a fully articulated assembly that transforms from a Cupcake CNC to a Bre-bot.
I started with a snap-together design (see the attached concept sketches) but migrated to a bolt-together kit for various reasons. The final design allows for fine adjustment of the joint tension so the transformer can stand in any position but still be movable, positionable, transformable!

See the animated transformation here: jmillerid.com/wordpress/2010/05/cupcake-cnc-transformer/

Modeled in NX6, rendered and animated in Modo, .stl files cleaned up in Blender, exploded view created with Rhino and Illustrator, sketches with Sharpie.

Here is a small toy elephant modeled in VectorWorks. I have included other versions of the file for people to play with.

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?

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.

The ultimate spare parts kit to keep your extruder printing day in and day out. Enough parts to make a complete heater barrel assembly, or replace replace other key components.

This is my first model to this forum, so be nice :)

I design this her wind turbine for the desktop. There has been a solar panel which generates electricity on to the little engine that sits up in the turbine head.

This is a badge for your 3d printer. I got the idea from Cory Doctorow's story called Printcrime.

I made two versions of it, a has just a border that holds the letters, b has a solid backing. I'm not sure which one is better.

Continuing Star Trek themed logos.

I designed this necklace to give to my girlfriend.
Hope she doesn't see it on here before I give it to her :)

I made it in blender, and for some reason couldn't get the top tube to connect to the bottom half properly, but it still printed fine.

It has a 6mm tube with 4mm hole for a chain.

I printed in PLA, which looks soo good.

If you have a cheap-ass car like my VW Polo'91 which is born without a cupholder, this is for you.

For the last 4 monthy, when people have asked me why I'm building a 3d printer, I have answered "so I can make stuff - like a cupholder" so the succes-criteria of my reprap project has been to print this very object.

So my 3D printer project is hereby officially a succes!

This is a Peristaltic Pump designed in Sketchup. I have tried to design it with an eye towards printing on a MakerBot, but do not own one so I cannot test at this time.

It should accept 3/4 inch hose with a 1/8 inch wall thickness.

This is the female part for thingiverse.com/thing:1416

Version 1:

I cleaned up some errors in the STL of the original
using NetFabb-Basic (Linux).
netfabb.com/news.php?nid=10

Improved version 2:

* The large bridge got some pads the filament can "land on" because the first few strands just fall down and make a mess inside the object with version 1.
* The smaller bridges got even shorter by rounding the walls inwards
* the clip is a few mm shorter, allowing the male part to settle easier even if not perfectly printed/cleaned.

Notice: This is a project in development, and I intend to improve it over time. This draft will work, but it's hardly ideal. Caveat Emptor!

Update Jan 31st: I've uploaded Version 2, which is pretty much the same as 1.5 (which I've removed as a result) but comes with the "Hex Key Holder", which can be fitted with a standard screwdriver bit from a powertool to act as a crude "center". My experiments with using two such centers to drive the lathe weren't great, as one invariably ends up spinning and the piece stops. So it looks like the required parts at present are: Two Bearing-End-Body Sections, two Bearing-And-Tool-Fittings, A Boltplate and a Hex tool holder. You'll also want a Dremel Rest and a length of MDF/wood to bolt it all down to. And you'll need googles, and perhaps gloves, and a lot of sense.
For now, it is left to the user to figure out spacing of the body sections and how to align them. I'm working on improving that. :)

More Update: Really bad video of me demoing Microlathe: youtube.com/watch?v=6XXN6UkrnIw and a shot of the finished piece of dowel on my Twitpic: twitpic.com/y8jnl
Also, Microlathe was featured on Makezine! blog.makezine.com/archive/2010/01/tiny_printable_dremel-powered_lathe.html

Microlathe is a little dremel-powered woodturning/watchmaker's lathe that can be printed and bolted together with all those leftover M3 nuts and bolts that came with your Makerbot. In addition to the M3 nuts/bolts, you only require a 608 bearing (I got an extra one with my Makerbot) and an 8mm diameter spring to fit the bearing-end. You probably don't even need that spring.

So, if you have a Dremel handy, you can consider this "The Lathe That Came Free With The Makerbot"!

Microlathe is Parametric, and makes use of a "Global Parameters" script from which the others derive shared traits such as the radius of the bolt plates, etc.. you could try printing a larger one, but bear in mind the limited space you have to print the body portions, which are already quite large for a Makerbot.
