my 2 souvenir keychains were waiting when I returned from the
(fantastic) Web3D 2013 Conference.

Photos attached. Colors were not an exact match but sorta close.

Problem: when I showed them to people and they examined the
items, the plastic edges started snapping off despite just normal
touching.

Warning: Colored sandstone material is brittle and not suitable
for daily use. Strong + Flexible white plastic is better material
for 3D printing.

The CAD group will continue evaluating the strength and usefulness
of various 3D printing options using X3D.

Sorry it didn't meet your goals. We've had medium luck with them as
keychains but usually a really boxy variety.<br>
<br>
On this page we list the material properties<br>
<br>
<a href="http://www.shapeways.com/materials/sandstone">http://www.shapeways.com/materials/sandstone</a><br>
<br>
We list the strength as low and say this: "<span style="color:
rgb(117, 115, 114); font-family: 'Helvetica Neue', Helvetica,
Arial, sans-serif; font-size: 16px; font-style: normal;
font-variant: normal; font-weight: 300; letter-spacing: normal;
line-height: 24px; orphans: auto; text-align: start; text-indent:
0px; text-transform: none; white-space: normal; widows: auto;
word-spacing: 0px; -webkit-text-stroke-width: 0px;
background-color: rgb(247, 246, 245); display: inline !important;
float: none;">The printed product is a hard, rigid material that
is slightly brittle and not suited for structural parts under
great load. However, they are great for little figurines and
models of your favorite video game avatar. Some of our most
successful products have been made with this material! Please keep
in mind that Full Color Sandstone is brittle so be careful with
your prints."<br>

Likely the most applicable material for keychains is the stainless
steel. <a class="moz-txt-link-freetext" href="http://www.shapeways.com/materials/steel">http://www.shapeways.com/materials/steel</a><br>
