Just a simple chess set, with some abstract chess pieces.

Perfect for relaxing after a hard day in space. 1:18 scale. A bit oversized to fit that bulky space suit.

Update: I need to resize this piece slightly to fit the makerbot astronauts. The chair is useable without the seat attached. Look for an update soon!

A little sci fi, a little retro - this television brings a little entertainment to our extra-stellar journey. My only concern is that children might not actually recognize this vintage device as a TV :) 1:18 Scale

This is version 2.0 of a 3-digit, base-10 register for an electromechanical computer I'm working on. It is stepper-driven, and works like a 3-digit counter, counting from 000-999 before rolling over. When all three digit wheels read '0-0-0', 3 reed switches will close and a circuit will be completed to detect the condition.

This one uses fewer parts and has at least been slightly tested. It also has larger digit surfaces for better visibility, and comes with printable labels!

Anyone who has operated a laser cutter knows that the surface to be cut needs to be as flat as possible.

This simple clamp helps you to level the sheets of wood, acrylic, etc when laser cutting.

The shaft is 5 mm in diameter.

A rebuild version of the Plywood Crate made by Joris van Tubergen.
thingiverse.com/thing:1512

I made it so that the parts can be clicked together into a box, it also is stackable, you can build a tower of these.
The source file is for a lower sized version of the box. You can modify the file to fit the size you need.

Material used: 3mm plywood

After I added the tapered mouthpiece to the whistles, and with the hotdog-red ABS, these things remind me of a toy wienermobile I used to have. Thus the name.

This panflute is slightly more practical than the one it's derived from. The curved shape is easier to use than the circle, and I added a bit of taper to the mouthpiece to make it easier to blow on a single whistle. Still not a practical musical instrument, though!

This one has a diatonic scale (CDEFGABC) instead of chromatic like the other one. I had to learn the OpenSCAD lookup() function for that!

These bed holders/corners aim to solve the dreaded XY wobble arising from crooked threaded rods. They also prevent the upper bed from shaking with respect to the lower bed on the 3 sprung M8 bolts. Finally they allow fine bed height adjustment at 4 corners rather than just 3 points.

This is version 15 of my design and the best so far, but it does not remove wobble 100%. I am very receptive to ideas to improve it. To give you an idea of my early designs, here is a youtube video of version ~8:

youtube.com/watch?v=LSeArlGSxtA

Installing these will be a hassle the first time as partial disassembly is required to remove the original bed holders. However my replacements are designed to be easily upgradable so please bare with the pain :)

I realise there are a lot of steps below, but it is quite simple and a lot of it will be obvious just by looking at the photos. The only tricky parts you need to obtain are 12x linear bearings (the same type used on the X and Y belt idlers) and 8x 35mm-long M3 bolts. These quantities are for a full installation of 4 bed holders, which I recommend as it would be tricky to mix and match these with the original bed holders.

PS I have quite a few bearings and 35mm M3 bolts left over, if anyone in Australia wants some, just send me a message.

Johnson polyhedra have faces composed of regular polygons: triangles, squares, pentagons,hexagons, octagons and decagons. There are only 92 such polyhedra. Instructions for making paper models are available, but with stl files one could print more durable examples.

I recently came across the netlib library of polyhedra at

netlib.sandia.gov/polyhedra/

which includes the Johnson polyhedra. I was pleased to see that it would be easy to convert the files to openSCAD polyhedron comands. Polyhedron commands are
a compact way of describing a polyhedron and, when executed, output an stl file.

I wrote a fortran program to convert the files; however a few files had errors. I had corrected most errors with openSCAD's unusual, but marvelous, "thrown together" mode when I was informed that the errors had already been noticed and corrected by George Hart

georgehart.com/virtual-polyhedra/netlib-info.html

There is a link on the George Hart page to a set of VRML files which display the Johnson polyhedra with color coded faces. References are also given.

Using the corrected files I was able to finish the conversion. You will find the 92 scad files in Johnson_Scad_Files.zip and the 92 stl files in Johnson_Stl_Files.zip.

To get a large version of the polyhedra it is best to print a hollow structure. Five examples of hollow polyhedra stl files are included here together with a sample openSCAD file, hollow_j03.scad.

Replacement for the acrylic single-head Rapman extruder carriage.

This design incorporates a fan duct that more effectively cools the area being printed, reducing curling and melting.

Also holds the extruder fastening bolts securely, without them loosening and turning like the standard ones frequently did on my Rapman.

The pins in this version are a little stronger and their slightly different shape makes them easier to insert and less likely to break. It also lets you make pegs which are printed horizontally so they are much stronger. Pegs can be used to join two parts that have holes in them. The pinholes also now have a small bevel in them to help make it easier to insert.

The syntax is totally different as well. It was kind of dumb to use global variables in the last version, now you pass the variables to each method so it's easier to have pins of various sizes in one project.

This is a fun project I started during the christmas holidays.

I combined thingiverse thing no 10650 with a yoda figure from the 3D galery.
The details have been reduced to make the HQ yoda printable.

Small (and dirty ;) ) script to convert grayscale heightmaps to stl models. Usable for landscapes or terrain prints.

Very much a work in progress! This is an odometer for filament! It should measure filament by the centimeter so you can have a real measurement for filament used! The base it attaches to slides on to the counter assembly, so you can chose different mounts for it, but the first mount is for a ToM endcap.

I'm currently printing the first set of parts to validate the design, after some tweaks, I'll upload the first working design to share and build from!

The next version will have a second resettable counter. I will also provide just the counter mechanism as a separate "thing" once I make sure everything works okay.

This is a 3-digit, base-10 register for an electromechanical computer I'm working on. It is stepper-driven, and works like a 3-digit counter, counting from 000-999 before rolling over.

Artec has quite the fancy collections of 3d Scans over at artec3d.com/gallery/3d-models/ .
This model is of the scan of Soppho's Head. I think this model is absolutely beautiful and was thrilled to find it. The STL has been given a flat bottom and fixed for holes in netfabb.

I printed her in White PLA from ProtoParadigm. At arms length she looks like she was cast in plaster.

Here's something that should make plastic life a lot easier. Fuse parts, smooth, shine and texture prints, even cast ABS at room temperature.

Build for a Halloween costume. Started out as Yodas lightsabre but I decided to embellish the detail a bit.

The Skymega is an electronic board for programming printbots. It is open source hardware, designed with the open source tools Kicad (we have named this kind of hardware as open source squared). It is based on the ATmega microcontrollers, so it is Arduino compatible.

Video of the Stead i Cam in action: youtube.com/watch?feature=player_embedded&v=PDLClM5rk5o

The Stead i Cam is designed by Frits Stam en Koen de Greef

features of the Stead i Cam:
+ removable / adjustable camera plate
+ design incorporates a feet for easy storage
+ weight swivels to compensate for an unbalanced camera
+ air bubble for leveling the camera
+ adjustable handle position with a screw thread which allows for very fine adjustments of the center of mass
+ light weight design

This project originated from the urge to create tools that help designers create professional results in times of budget cuts. With ‘Tools for Design’ we aim to create a community that helps in the development of instruments used in the design process. The Stead-I-Cam is an example of one of these tools. It supports smooth and professional moving video footage. It is created from a single sheet of laser-cut material, making it easy for any student to create and assemble. This open-source project cuts costs for such a professional tool and makes it accessible for every student / diy'er.

We love to see your own Stead i Cam so upload a picture of it!

I'm making extensive use of OpenSCAD. The only problem I found is that the polygon function is hard to use. I rather draw my polygons visual. So I created a simple polygon editor for OpenSCAD in Javascript+HTML.

Following the idea from the "OpenScad Polygon Generator" by "PieterBos" thingiverse.com/thing:9290
But then working for any OS, any browser, without fuss. You don't even need to install anything! (might even work in mobile browsers)

Hi,

this is a complete printable eggbot
it is also work in progress (for now) but submitting it next week seems a little bit silly to me.

for now, the egg mountings are still to be designed (maybe we can 'borrow' them from somewhere).

!! AND SOMEONE DID, see hbs's page thingiverse.com/thing:13960 for those things, Thanks.

new pen holder (PenHolder-7.stl)

This is a square solid inside a triangular hole within a triangular solid inside a square hole.

The predecessor to this design featured a triangle inside a square hole within another triangle inside a square hole. It sounded nice but the square hole broke up the symmetry of the triangle, plus it didn't exploit the reciprocal capability of a reuleaux triangle to contain a square inside a triangular hole.

Using MS-PAINT to make 3D designs? Would Bill have imagined that 26 years ago?

Two nuts travel opposite directions on the same thread! As seen on YouTube! youtube.com/watch?v=o-fPsvqjqZI

Update 27 Oct 2011: I've uploaded a new trick nut triplescrew_backward_floor.stl which eliminates superfluous slack and reduces the overhangs to where they might be buildable on a Makerbot.

The YouTube video inspired Thingiverse user msruggles to design his own "Screwy Screw" thing. The STL files below are the originals, which were used to make the video, which inspired msruggles to make Screwy Screw, which inspired me to upload the STL files below...oh gosh, I'm completely lost!

Don't know how it works? Obviously there's a trick to it, but I encourage you to try to figure it out before you "spoil" the fun by downloading the files. Try designing your own!

Climbing hold for indoor rock climbing. Accepts a 3/8" bolt.

The openscad puts random spheres (with random offset and number of facets) around a central cube to ensure a good attachment point. Play with the seed, add more spheres, go nuts!

Tested on a bouldering wall, SportRock in Sterling VA. I think it'd be better to enlarge it, but of course I was worried about strength. The size that it is, you can't really crank on it so it's stable, if a bit slippery.

This is a working zipper mechanism. I printed it as an experiment, inspired after the zipper on my wife's coat broke. (I don't think I can print a replacement, yet.) There might be applications to join small sections of a structure to make a large object, but mostly it's a toy.

A simple and strong quick release for you to quickly mount and dismount your camera, or whatever, on anything you want. I am using this to mount my DSLR on a time lapse panning rig.

UPDATE
I have added a redesigned handle that uses less material and can turn left or right.

Another good use is to place this on a tripod that doesn't have a quick release.
