This is a adapter to fit standard exhaust hoses to the Full Spectrum 40W Hobby Laser and the HPC LS3020 Laser Cutter. It might probably fit a few other laser cutters from China as well.

The standard exhaust fans that come with these lasercutters are not all that great. They are inefficient, leaky, have a non-standard hose fitting, and block access to the back laser compartment. This adapter allows you to fit a standard exhaust hose to the laser, which can then be connected to some proper air filtration equipment.

It was created by Alexander Brock in the RaumZeitLabor hackerspace in Mannheim, Germany, for their FS laser cutter.

possible use as a candlestand

This is George Hart's reconstruction of a 16th-c. wooden puzzle, currently in the Schloss Ambras Museum. Print out 76 units and reconstruct the original! A full description is available at georgehart.com/rp/torzle/torzle.html.

This is a model of a Turk's head knot. ( en.wikipedia.org/wiki/Turk's_head_knot ) It is a 3-lead, 5-bight knot (3x5), with a triple strand. In the first file, I added a small base to the bottom to help with printing. Without the base, the 5 initial contact points tended to detach and the overhang on the bottom is pretty extreme.

The example was printed on a printrbot (thanks Mike!) from white ABS. It measures approximately 50mm in diameter at its widest point.

The knot path was generated via a Sketchup ruby script I wrote, and then the strand cross-section was extruded along that path. This created some very complex objects and took some work to figure out how to deal with overlapping areas and get a manifold object.

I have generated other lead/bight combinations, but this was one of the nicer-looking early attempts.

Edit: I added the Turk's Head .stl without the base, for those that would like to add support material, or try and print it without a base.

Just would like to publish it, and since the "Made one" feature is not working on original I published as a new thing.

duh duh DUH dun!

Beethoven looks pretty grumpy for a really awesome bust you can print on your MakerBot, eh?

A miniature castle.

This is an adapter to attach Brio style wooden toy train tracks to Lego Duplo compatible brick constructions. The idea was to adapt between two incompatible commercial toy systems, something that would never happen in the retail world.

Useful for building elevated train tracks, subway stations, Highlines, and crazy buildings with trains going through them.

This is a derivative of "parametric lego duplo by danielkschneider"

Update: 2010.10.22 I updated the file with a much cleaner rebuilt STL.

A simple vase/tea light (LED only!) or hollow form based on a Koch Snowflake with 3 iterations.

I developed this sculpture during the Generator.x 3.0 workshop with Marius Watz at iMAL in Brussels, Belgium.

imal.org/en/activity/generatorx3

Rebuilt based on CloudMaker's version (which is based on the sculpture LOVE by Robert Indiana).

Now the letters slightly overlap, making the print less fragile.

Done with OpenSCAD. The single letters are in a dxf and then extruded, so you easily can do some finetuning if you want to.

I removed the files after seeing new user agreements. I don't like the feel that Thingiverse owns the design. Files are here reprap.org/wiki/Prusa_Mendel

Shower head holder that can be clipped onto a rail.

There's also a variant for wall mount: thingiverse.com/thing:10407

Basic, printable component of a vertical wind turbine. Easy to print on a Makerbot without any support structure. You can print as many as you like to make a turbine as tall as you please!

Yay! Ninjas in your kitchen! This is a printable "Shuriken" fridge magnet.
SHOW EVERYONE YOUR NINJA PRINTING SKILLS! :-D

Updated: Version 103 has more user-friendly parameters. The 103.stl has an altered impact angle. So if you plan on printing more than one: Download and print both STLs for a more natural "ninja attack" look :-)

!! 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.

I adapted stickoutrock's Crosslink Ellipse Gears to be printable on a 3D printer. It's similar to natetrue's version ( thingiverse.com/thing:1538 ), but I created a completely new design in OpenSCAD, which uses a different type of joint, which should be more robust. The joints also do not stick out of the holes in the ellipse gear, avoiding the gears to get stuck during the rotation.

Here is a video of this thing: vimeo.com/18244936

Not really meant to be a functional design, just played around with OpenSCAD's rotate extrude function. But makes a nice demo object.
Based on one of OpenSCAD's example files.

Inspired by TeamTeamUSA I modeled my own version of the World Cup Trophy. I printed one for the Germany game tonight. I just need to buy some gold paint now.

3d printable model of a space ship inspired by the famous space saga

Modeled in Blender 2.5 alpha.

Updates:
v6: Scaled the model up a bit, the wings where too thin for skeinforge
v5: Fixed stl, contained some invalid geometry.

This is an adapter that lets you attach a Philips ToUCam web cam (model PCVC740K) circuit board to a telescope eye-piece opening, allowing to use the web cam to directly "see" through the telescope.

Update 25-May-2010: Removed enforcement ring to have the sensor closer to the telescope
