The quality is very good. Especially I like the look and touch of Prime Grey material. However it is not as strong as I want and snap joints would break quite quickly.

Polyamide is rather more strong and flexible but doesn't have this "luxurious" touch and gets dirty very fast. I will ask the factory to paint it next time.

I had to fix the AUX button with a rasp because it was too big (it might be my model or varnish the factory used). I will fix the model to avoid this in the future. There are also some other minor issues with the model (the screen appears a little bigger than original and the space left for the Power button is also too big, but those are not big issues).

I've printed the speaker top part in ABS also, but the quality was not as good as Polyamide.

I have successfully installed my GTA02 board into the case (keeping original speaker parts because they are a little different to give enough room for wifi) and will use it for some time and report back. I don't have a GTA04 yet because it's also not being shipped to Russia. I'm now figuring out the way to by it by someone in between, but will wait for a case kit first.

Now about the prices. It is expensive, especially the buttons printed in Transparent Resin which costed me 55€ each. The front cover (Prime Gray) was 22€, middle part and back cover (Polyamide) was about 36€.

3D-printed case attempt

This is my first attempt to create a complete case using 3d printing technology without sacrificing buttons and the hole. My work is based on official Openmoko CAD files as well as on Lukas Märdian's work (http://blog.slyon.de/2012/01/02/building-a-case-for-the-goldelico-gta04/).

The first attempt was unsuccessful: the hole was too big and couldn't fit. However I'm not giving up.

The part shown on photos is printed by i.materialise in polyamide. The part fells as strong as the original one (even the small details are good) but not finished very well which is not a big issue.

I will provide the sources when I'm ready to release them.
