With these connectors and different lengths of cheap and common 1/2" PVC pipe, you can construct the frame of a personalized Wendy House (or playhouse) for your miniature, chronologically-impaired, humans!

The version I have built, creates a simple, 'traditional', gable-roofed, playhouse frame.

NOTE: The gable end pieces are temperamental when I try to print them. The rotation I have them on the print bed is the only rotation that it doesn't break horribly with. Otherwise, the print-head knocks the model at the top of the tear-drop holes and shifts itself across - creating a geology-like shear across the model

I have included the SketchUp model which shows the sizes of the house. Should you wish to change the lengths of the pipes to scale it up or down for your own use, this model should help if you don't want to just do the maths. (The gable is 45 degrees for ease of trigonometry.)

(And the reason there's two extra struts on the bottom of mine, is that I was intending to wear this hut as part of a costume for Halloween - Baba Yaga's Hut, complete with chicken legs and miniature witch inside. I didn't finish it in time!)

This is an exactly proportional copy of the companion cube from portal, as traced from a screenshot.

There were a few cubes already on thingiverse which I've printed out dozens of, but they all had some issues with printability or proportionality. I think I've solved all the problems with this version.

This version is flat bottomed, and has no significant overhangs over 45 degrees.

It is carefully designed in Solidworks so any changes can be quickly and easily made. I also included step files since Solidworks is pretty unfriendly to a lot of other programs.

The default size is exactly 1in^3

The Cube in the thumbnail was printed by a Fablicator.

More Eggbot plots. pattern2-767.svg is the nicest of the three. It was generated to be 1125 pixels high and then vertically shrunk to 66.667% of its original height. That then gives an egg-suitable aspect ratio.

The other two plots, pattern2-800.svg and pattern2-1000.svg are, respectively, 800 and 1000 pixels high. They are more appropriate for plotting on spheres as they have 1:1 aspect ratios. The supplied Python program generates the 800 pixel high variant. Change the HEIGHT variable setting for a 1000 pixel high plot.

This drawing is less demanding of plotting precision than an earlier, similar version I have posted. This version fully draws each local region of the egg before moving on to the next region. While this makes the plotting time a bit slower (but not by much), it reduces the amount of plotting precision needed. (The prior version of this drawing was optimized for speed but made the egg go through many full back and forth revolutions.)

If you still have plotting precision issues, you can slightly stretch the drawing horizontally by, say, 5 pixels. (If that's not enough, then iterate by stretching again.) Just select layer "2 - black", select all in layer, and then use Object > Transform. In the Transform sub-window, use the "Scale" tab and set the units to "px" (pixels). You may see that the initial width isn't exactly 3200 pixels: that's because (1) the drawing is wider than 3200 pixels as it wraps around the egg, and (2) Inkscape takes into account the stroke width of the lines.

Alternatively, you can remove a column or two from the drawing if you are having plotting precision issues. The result still looks quite nice.

For plotting on spheres, you will need to rescale the vertical component of the drawing: it is presently squashed vertically so as to make it suitable for plotting on eggs. Rescale the vertical dimension by 100% / (0.666666 * 0.95) or 157.89%.

The SVG files pattern-20.svg and pattern-16.svg have, respectively, 20 or 16 "stars" running horizontally around the egg. Thus the -20 file has more stars. The interactive Python script pattern.py may be used to generate additional SVG files with whatever density of stars you'd like, and with or without vertical compression for eggs.

...or "omelette" if you prefer.

These files are for plotting an omelet recipe on eggs using an Eggbot. Use the file omelet.svg or omelet-1-serving.svg if you park the "pointy" end of your eggs at the egg motor cup. Use omelet-flipped.svg or omelet-1-serving-flipped.svg if, like me, you park the fat end of your eggs at the egg motor's egg cup. (Less slippage when you do that, eh?)

Note that the text is sized such that you don't need a nano sized pen tip: I used a Sharpie Ultra Fine for the pictured egg.

So how many servings for omelet.svg and omelet-flipped.svg? Those two files have a "2 serving" recipe which calls for two eggs. If you desire a more self-contained recipe, then go with the "1 serving" variants. And, if you need nutrition info, well just see thingiverse.com/thing:7232 and then mentally add in the 2 or 1 Tbsp of cream and 3/4 or 1/2 Tbsp of butter. (Butter is about 100 calories per Tbsp and there's about 50 calories per Tbsp for heavy cream [the yummy stuff].)

Bon appetit!

In need of nutrition information for your large eggs? Then this drawing is just what you've been looking for!

This is a 3200 x 800 pixel plot intended for plotting with the Eggbot.

P.S. The text was rendered using the new Hershey Text extension by Windell Oskay and distributed with the latest Eggbot software release. It may be found in Inkscape under Extensions > Render > Hershey Text (after you update to the latest Eggbot software). The utility of that extension is not limited to just the Eggbot. Among other things, it provides nice, non-filled, single stroke fonts ideal for use in CNC and CNC-related applications.

At the flee market this weekend I found a board game from my childhood, so of course, I bought it for my child. Unfortunately it was missing one of the plastic feet for the game pieces. So, I broke out the calipers and got scading. The piece is designed for the great game Mausefalle (http://boardgamegeek.com/boardgame/25097/mausefalle), but it should work with little or no modification with many a great board game with cardboard cutout game pieces. (ie: Candy Land)

Now I just need to find the rules for Mausfalle, since I don't remember how to get out of the mouse holes...

Based on Sandy Noble's Polargraph: polargraph.co.uk

This is the first pass at a printable gondola for a Polargraph. It works, but it could use some tweaks.

Anyone looking to improve it: the lower section arms are a little thin, and the spot for the captive nut isn't exactly sized right. I'd also beef up the upper chain mounts, as there's not much plastic outside the hole.

The motor brackets and pulleys I'm using can be found here: thingiverse.com/thing:12403

I've been making action figures lately (see tekeian.posterous.com/pages/action-figures). Here is a version for Thingiverse.

I've printed 80 action figures of various designs. One of the goals is a quick finish and assembly time. Only a flat file and an X-Acto knife are needed for raft trimming, then glue it up.

The arms can be articulated by gluing some filament to each arm and running them through the hole in the body.

The hands (or claws) can hold objects with a ~3mm edge.

You can't take the sky from me

These are a selection of elements that can be used with the ancient miniature war game rules De Bellis Antiquitatis or the fantasy version, Hordes of the Things. They may also work with Field of Glory, but I'm not very familiar with that game system.

The most current version of these rules can be downloaded from the developers website (http://www.wrg.me.uk/) in the "History of WRG" section. They are planning to release a new version for sale later this year.

These rules are sol as rules only, leaving it to the players to acquire figures from whatever vendor in whatever scale they choose. So why not just print your own!

I settled on 10 mm scale after trying 15 mm and 6 mm. At 15 mm, the resolution limitations of the printer are rather obvious. At 6 mm... well, I just wouldn't want to paint 40 little men for one element of troops... 10 mm is a nice compromise and it give a good impression of massed troops.

So far I've uploaded 4 of the 16 element types in the game. I hope to design the rest and upload them soon. There are a few additional elements in HotT such as dragons and Behemoths that I may or may not tackle, but I encourage anyone interested to jump in and supply their interpretation of these units!

Since the thingiverse needs good robots to fight the bad ones, i give you R2! I've modeled the full scale version in inventor and put the files here. I've also made an attempt to make it printable. However, since my printer is currently down for repairs, i'm hoping someone else will give it a shot and let me know how it goes!

Obviously design credit goes to lucas film, but the 2d design files came from the r2 builders group, and the 3d is the result of days and weeks of modeling and guessing. May the force be with you :)

This is the building I live in in Boston (also the building we started my current company wayfair.com in). Pretty fun to have a mini replica of where you live. The overhanging deck in the back came out suprisingly good!

This is the first release of the Boot-strappable Open Laser Cutter project that I've been working on for the past few months. The goal of the project is to construct an open design laser cutter with a large cut area (about 1 meter square), for about 5%-10% of the cost of a commercial system. The design draws heavily from other open laser cutter projects out there (such as the Buildlog 2X Laser Cutter) in using inexpensive aluminum extrusion and optics for most of the structural frame, while here most of the custom parts are 3D printed from ABS.

The printed parts represent about 10 hours of total printing time on a Makerbot or Reprap, and have been designed with the hope that they would be of general utility to anyone printing out a large CNC system -- not just a laser cutter. These include parts such as NEMA17 motor holders that mount onto t-slot, idler brackets, pillow block bushing mounts for motors, idlers, and shafts, and so on.

This is a model of the Space Shuttle that stands over 12" high.

It started out as this model from Google's 3D warehouse.
sketchup.google.com/3dwarehouse/details?mid=4c41b6547d241ffd9aa9d7f676c1fd7e&prevstart=0

All the parts come apart so you can configure it in many ways.

- On the launch pad fully assembled
- Launched with boosters attached
- Boosters detached - just the Orbiter and fuel tank
- Orbiter by itself

Tek Jansen, based on his appearance in Stephen Colbert's Tek Jansen #1 from Oni Press ( onipress.com/title/stephen-colberts-tek-jansen-1 ).

At long last, everyone in the world (ok everyone who has access to a 3d printer) can have their own bust of America's greatest entertainer and statesman, Stephen Colbert.

Even better, you can use this model and your favorite 3d modeling software to add Mr. Colbert's face to objects which were formerly lacking in Colbert heads, like bannisters, umbrella handles, toothpaste squeezers, and rabbits. (To name a few.)

Made with a Polhemus 3d scanner at the Colbert set on 6/6/2011.

Easter and finishing Portal 2 inspired me to make this basic turret template for use with the Egg-Bot. The back of the design has one of the famous quotes by everyone's favorite, child-like home defense product.

Replaced hard coded numbers with named variables

Turret themed chess set for a board with ~1in squares.

I'm working on making a chess board and due to certain constraints, I needed smaller than usual chess pieces (~1" base). Seeing how I was already going to be making them I figured I'd create my own design instead of just scaling someone else's. I purposely stayed away from too many details on the pieces because my printer and I are in a disagreement regarding calibration and I don't want to spend my all my free time cleaning up prints. I would love to see someone detail these out (wink wink nudge nudge).

This caterpillar track is the first step towards designing and building a printable mobile robot. My finished robot will have four of these modules, but many other designs are possible. A single caterpillar can function on its own as a simple robot that can move forwards and backwards; two modules can be joined together to form a tank-like machine, etc.

This thing is designed to work with a Futaba 3003 servo (modified for continuous rotation) and uses O-rings to make up the transmission and the caterpillar itself.

Transmission O-ring: 3mm thickness, 60mm diameter
Caterpillar O-rings: 3mm thickness, 124mm diameter

This O-ring system was chosen because it was easier to prototype, but it has evident drawbacks. In future revisions I will change it to a "solid" rubber track.

Note that the pictures of the printed robot at the bottom of the page are missing the reinforcement parts. I will upload new pictures as soon as I modify it!

This is an extrapolation of the now infamous Penrose Triangle illusion 3D model (http://www.thingiverse.com/thing:6513). If you had trouble getting your head around that one, you're not going to find this one any easier! :)

Where the triangle used 9 cubes, this arrangement uses 31 cubes to make a larger sorta-notreally-cube.

All versions are parallax-corrected for a viewing distance of 40cm.
(the larger ones are not simply scaled up versions of the smaller ones)

!! New version penrose5.stl with a couple of wayward vertices fixed !!

This is a 3D-printable version of the Penrose Triangle illusion, based solely on the 1934 design painted by Swedish artist Oscar Reutersvärd. The design also appeared on Swedish postage stamps in the early 1980s.

I created this 3D design entirely from scratch using the process outlined in the "Instructions" section below. This work is based solely on Oscar Reutersvärd's design, although some elements are inspired by the Hollow-Face illusion discovered many decades (if not centuries) ago.

This model contains a number of notable improvements over previous 3D representations:

1) It is parallax-corrected for a viewing distance of 40cm, i.e. it will look exactly like Oscar Reutersvärd's design, with cubes lining up on all 3 sides simultaneously. This is a great visual improvement over previous versions, which only lined up on 2 sides simultaneously.

2) It has been resized (to 99.43 x 99.65mm) to make maximum use of the Makerbot build envelope.

3) The top edges are now tapered so as to make the most of your printer's capabilities. The better your printer, the sharper the edges will be.

4) I own the copyright to this 3D design, and hereby distribute it under the "Attribution/Non-Commercial/Share-Alike" licence for all non-profit parties to print, improve and share.

This piece was inspired by some artwork at my friend's house, hence I am naming it after her :)

It is a beautiful piece which will confuse most people the first time they see it, as they try to figure out which part leads to where and how!

This started out as an exercise in using Greg Frost's awesome involute bevel gear script thingiverse.com/thing:3575, but turned into a rather pleasing worry-ball type thing. It's also clearly influenced by Greg's broken heart thingiverse.com/thing:4683, though this has octahedral gears rather than dodecahedral, so they all mesh with each other and spin. My favorite thing about it is that you can grab two opposite gears and twist them, making the center with the other six gears spin rapidly around.

This edge lock system for paper and plastic works great for realizing meshes from thin sheets of material. It avoids the negative accumulated error common with the classic glue and tab method of construction. Instead the edges have enough freedom to adjust towards the perfect position.

Getting the Y axis belt tight enough can be a real pain. That's why I've designed this printable upgrade to allow increasing the tension on the Y axis belt / pulley by turning a screw.

You can find my X axis belt tensioner here thingiverse.com/thing:1673

V1 - Based upon a single captive nut.
V2 - Fixing an alignment issue.
V3 - First printable version. The smaller piece that holds the captive nut was too long.

2010-01-23
V6 - Same concept, but a different design using two captive nuts on each side of the Y axis pulley. My test print is suffering from some X stage problem, so the prints aren't coming out right yet. However, I wanted to post this in case I could get feedback from others.
2010-01-25
V7 - Same concept with a few improvements.
