You can easily order your GTA04 case at Shapeways.
It will cost about 55€ (+shipment) and should be shipped in approximately 2 weeks:
- Black Strong & Flexible
- Recommended: Colored material, little rough but nice feeling (becomes smoother after a while).
- White Strong & Flexible
- Default white prototyping material, little rough but nice feeling (becomes smoother after a while). Gets dirty easily.
- Colored Strong & Flexible “Polished”
- The polishing process influences the fit.
Note: The front conver is designed to hold the replacement GPS antenna (Taoglas AP.12F.07.0045A), using a sharp knife it can easily be modified to fit the original GPS antenna, though.

Also have a look at the auto-generated CAD files for the GTA04a5, which might have a much more precise fit than this manually adopted files: download.goldelico.com/gta04/CAD
