GTA04 front cover
The part shown above was printed with the "Black Strong & Flexible" material. This part can be used as a replacement part for an Openmoko Neo or a Goldelico Letux 2804.
This 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.
