3D Print Filament Cost Calculator for Android - AriRobinson.ca/?p=106

I have built a simple Android calculator to estimate the cost of a part before it's printed. All you need is the size of filament you use, the cost / weight of a roll and the length of filament that will be used in the print. From that it shows you the cost of the part based on the density of the plastic being used.

I am looking for suggestions for improvements and other features you might like to see!
