Building a Case for the Goldelico GTA04

I just came home from my christmas holidays and found a nice, little parcel from Shapeways in my mail box. It contained my first experiment with the Blender 3D software and the Shapeways 3D printing service.

Update: Follow the efforts here: 3D printed GTA04 Case

The Story

A few weeks earlier I started to work on the original Openmoko Neo 1973 (GTA01) CAD files, as found at, with the intention of creating a 3D printable model, which I could print and use as a case for my new Goldelico GTA04 smartphone. To get started I got a Blender 3D crash course by a friend of mine.

First Attempt

As I never did any 3D work before I started with the easiest part – the battery cover:


This first prototype was printed using the “White Strong & Flexible” material offered by Shapeways. As you can see on the pictures, this material is a little rough, but still feels nice in the hands. Furthermore I removed the hole at the bottom, as it was pretty hard to design.

The printed part fits nicely on my existing Openmoko Neo Freerunner (GTA02) case, which contains my GTA04 board at the moment:


Future Plans

Now, that my first attempt was pretty successful, I plan to further work on this topic, to acquire a full case for my GTA04, so I can use the old case for my beloved Openmoko Neo Freerunner (GTA02) again.
As a next step I’ll modify the Neo 1973’s middle and front parts to be printable with a 3D printer and I’ll probably try to print them using a less rough material, to compare the results.

How you can help

If you like this effort, I’d be happy if you’d go to my Shapeways site (“SlyParts”) and order the first part of your GTA04 case, which will raise 1€ for myself, which I’ll use to order further prototypes.

If you don’t have a Goldelico GTA04, yet, you should take a look at the GTA04 Group Buy Tour, where we collect a batch of 350 orders which will be produced at once, so the price can get squeezed down.

If you ordered a part at my Shapeways site, please leave a comment here about which material you used and how it feels.
