The best triply periodic minimal surface ever!

I put a bigger one here.

[Note: This propeller propulsion add-on does not include a 3D printed Strandbeest, which should be bought seperately! This propeller does not fit the Ondula version!]

Theo Jansen’s 3D printed Strandbeest continues to evolve with the addition of a Propeller Propulsion system! The 3D printed Strandbeests can now walk autonomously, powered by the wind, just like Theo's full-scale Strandbeests. The new propeller add-on gives new and existing owners of these kinetic sculptures a new way to set them in motion!

The propeller addition is available as a separate kit, which can be mounted on the 3D printed Strandbeests. The propeller is compatible with the various evolutions of the Strandbeest, so existing owners of the “AGP” 5 and 7 model Strandbeests can use it as well. Consisting of 5 main parts, it can be mounted on the Strandbeest body in a few simple steps.
Also see our videos of the Strandbeest Propulsion in action, and the video with mounting instructions.

The 3D printed Strandbeest is sold separately.

A few tips to consider:

- Please look at our instruction video on mounting the Propeller Propulsion add-on, here.

- After mounting the Propeller Propulsion add-on it is best left mounted. Frequent dis-assembly can wear down the material which can result in play on the mechanism.

Tool, symbol or both?

The bits on this pendant are based on actual bit sizes - including an IKEA standard tool - so 'a bit cross' can be used for light jobs. Just remember the steel isn't tempered like 'real' tool bits and tolerances may vary.

I recommend using it with a red leather cord of about 78 cm/ 31 inch.

If you are new to the Shapeways website: to order you will be asked to create an account (it's easy).

I revised the Christmas Ornament RBS to have just a little more slope. I'm hoping it's enough to have the marble roll without problem. I added a few new things. This one has a circular base so that it should stand on its own. I also beefed up the frame to make it more durable. There's less rungs and a few more braces. I will have to print it and test it. If you just want one even though it hasn't been tested, please feel free to order but you're on your own. http://www.rollingballsculpture.net

You can see video of it here: http://www.youtube.com/watch?v=qUlLRtTp050

This apple was created following mathematical recipe found in 3d-meier.de (look under tutorials). Some of the parameters were exagerated to allow holes in the object so that only the 3D shell is printed instead of a filled object.  For reference, the height of the object is about 6cm.  Basic equation that you can use to generate this shape is of the family of a "Dullo":
 (x2+y2+z2)2-(x2+y2) = 0

What you need:
1. Equations (find at 3d-menier.de)
2. K3Dsurf (open source software, realize mathematical equations into shapes!)
2. Blender (open source awesome software for 3D mesh creation)
3. MeshLab (very easy to use mesh quatlity fixing software)
4. Patience and a bit of figuring out the software

Steps to making this Nifty 3D Apple:
1. Find the precise equation in 3d-menier.de
2. Download and install K3Dsurf
3. Use the equation provided by 3d-menier.de and copy it into the pa
3. Save the mesh using K3Dsurf
4. Import into Blender
5. Use Blender to give it thickness (because the equation is that of a thin shell), I gave it 1mm
4. Import the mesh into MeshLab
5. Use the Smoothing algorithms (I used Gaussian)
6. Upload into Shapeways and be ready to print

I would also recommend using:
FreeCAD !
