I received the antenna-centers from Shapeways today, it didn´t take more than a week from idea to actual device in hand. Initial testing show them to be a success, and just as I expected them. Now I can easily make portable antennas, without having to tie wires in knots and rats-nests to make them. The weight go them is around 5 grams each, so they´re not really noticeable even on hikes in the wilderness with a heavy backpack.
They are made in what Shapeways calls "
Strong & Flexible Plastic", which is laser-sintered nylon. How they will stand up to UV I have no idea, but these things are for portable use mostly, and they´ll last for years anyway.
