This ring has eight ternary crosses dirtributed aroud it's perimeter. As they go around these crosses make one full turn around themselves.

I suggest ordering it in Strong White and Felxible and painting it with nail varnish in a metallic color. This will give it a nice look (see picture).

This was my first object designed in openSCAD.

Decorative part, which may be used as sunchime.
If you turn it, from three directions you can see through and an interesting pattern emerges.
It is 60mm long.
The connecting parts are square and 1x1mm thin, therefore the material restrictions.

These are compatible to the rhombic penrose tile set.

This is the Broad Thorn Pendant.
(The ten necessary gemstones are not included.
You can get them for example from this unaffiliated shop: nahoppla-shop.)

It has two grommets, one on each end.
So depending on your taste you can wear it upright or sideways.
With 3.9cm length it is quite big and eye catching.

On each of the two twisted sides five 5mm diameter gemstones goes in.

You can even make it multicolored if you'd like,
but single colored designs are definitely more elegant.

Thorns are always assoziated with roses and they have simply to be red
so I've choosen red gemstones for the one depicted above.
It's wonderfully sparkling in bright sunlight.

length ............ 39 mm
approx. diameter .. 16 mm
grommet diamter ... ~4 mm
gem diameter ......  5 mm (not included)

It was only test-printed in unpolished silver. Note that especially the steel versions could have surface roughness that might prefent the gemstones from fitting in properly. Alumide Is very brittle and probably won't be polishable. If you really want to try it give me a note.

Easy readable binary encoded highly symmetric die (small version).
Optimal for printing in sandstone.
Still good for the detail materials.
In steel or glass the fine details might not come out very readable.

This die was designed so that the value representing markings
preserves all the symmetries of the cube-faces
namely one fourfold rotation axis
and four mirror planes per face.
 
The markings are encoded in binary.
But you don't need to know that to read it!!

Due to the quadruplication and overlapping
of the marks the die is easy and naturally to read for everyone.
Just count all pluses of the whole face and the minuses of only one edge and add them.

If you want to read it in binary and fully understand the system
here is how it works:
You read three bars from the center of one edge.
The bar in the center of one edge counts one (it overlaps exactly with its mirror image).
The bar between the edges center and edges corner counts two.
The bar near the corner counts four (it forms a plus by overlapping with its mirror image).

The grooves are intended to be filled with low melt enamel.

This part can be screwed in the small square holes of 7-league boots (7 Meilen Stiefel) with a single M5 screw (hexagon head).
With it you are able to mount a lightmod, a bottleholder or something else onto your Stilts.
I suggest buying two of them per stilt in the sturdy white or dyed Strong & Flexible material.

To get it nicely colored like in the picture or with your favourite colors
you need (tansparent) low melt enamel from a different source. Just google for it.
You can also mix finegrained glowing powder into transparent enamel, for a cool party ring.

You need 21 kites too to have a complete set.

A piece of jewelery wit a futuristic look.
It is based on the koch curve.
The hexagons are 25mm edge to edge.

A very simple recursive structure.
It may be usable for table settings, or whatever you can think of.
It is 120mm long and the bars are 1x5mm thick.

It was gernerated with two self- and mutual recursive functions.
the longest bar conects the "infinite many" disconnected parts of it's natural form.

Clearance testing part for different "crystallographic" orientations.

Meant for Strong White & Flexible!
/*
(markings: X-axis: one carve; Y-axis two carves; Z-axis three carves)
clearance = 0.1mm*c___
The small part has the different inner diameters.
The big 7-legged part has overall outer diameters of 3mm.
This is the list of the clearings for the different crystallographic directions:
*/

c100 = sqrt(3); // calculated
cx01 = c100; // 10x=x01
c11x = c100; // 11x=xx1

c010 = 0.2; // recommended
cx10 = c010; // x10=1x0
cx11 = c010; // x11=1xx

c001 = 2.25; // a little bigger
c0x1 = c001; // 0x1=01x
c1x1 = c001; // 1x1=x1x


//remaining clearance tests in only one orientation [110] or [111]:
c110 = 1;
c101 = sqrt(2); // 1.414..
c011 = 2.5;
c111 = 0.5; // powder clearing

Please ask if something's unclear.

With these tiles the rhombic Penrose Tiles can be freely intermixed with the Kite&Dart Penrose Tiles.

To get the grooves nicely colored you need low melt enamel from a different source. Just google for it.
You can also mix finegrained glowing powder into transparent enamel, for a cool party ring.

Scaled up version of Crossfractal-3D 60mm for printing in alumide.
This one is 90mm long.

I'am sorry.
Though it abides the minimum wallthickness for alumide (1.5mm)
Shapeways still won't print it because of it's aspect ratios.  
So I have to deacivate the alumide option. :(

Maybe painting a White Strong & Flexible print is an acceptable solution.
In Strong & Flexible also the smaller and cheaper 60mm version of it is definitly printable.
I know because I got a testprint.

This is a plate with the Haskell sign designed to be worn on the body.

If you don't know the programming language Haskell you can take a look here:
http://www.haskell.org/

It's slightly arced shape makes it optimal as the mainpiece of a headband or a wristband.

It's size is roughly 38x18mm.

The slits are 3mm in wide so that a leather strap can be feed through.
There is also a version with holes instead of slits aviable in my shop.

This two lightweight skeleton grids can hold twelve CCFLs (cold-cathod-fluorescent-lamps) in place.
Eight on the upper layer (in my case UV) and four on the lower layer (in my case white).

The CCFLs to use are the ones for case modding
with 1.5cm sidelength plexiglass cubes at the ends (I used Revoltec).
Once it's acomplished to get them all in their pockets at the same time
which can be quite tricky they are hold in place very thightly.
