I have been printing off the rest of the case.

Above is the printer I have been using, located at the Melbourne Hacker space. Below is it doing its magic.

Reprinted the bottom as well as the top, now with different filament colour.

Another view, outlining the tabs on the top part.
Below is when it parts clips into together.

This is the view from the side.

With the front view you can see the USB connecter was taller then anticipated, however, the parts were still able to clip into each other.

I have also printed a bottom case for the LiPo battery, which was a snug fit for the battery.

The red LED is only on when a battery is present and the battery is charging, otherwise its off.

Test of confidence, by powering from my computer's USB port. I have been using a cheap mobile phone chargers from this.
