Instructions
Just access to the Android Market(below), and install it into your Android phone.
market.android.com/details?id=jp.kshoji.stlviewer
You can download the STL file with Opera or some browser.
Default browser with my DesireHD, couldn't save STL file from thingiverse. I don't know why.
After downloaded the file, then open with the application.
Tap folder icon, and you can see SD card directory. Then choose STL file.
