New to sharing to the community looking forward to sharing more. I found some apps in the Google app store (for android users) that allows for simple mobile creation of 2d pictures that are then rendered into 3D .stl files. The program is called makerdroid. Then I wanted to preview it and had to install a viewer called graphite which worked really well to show a rotatable view of the object. With some setting adjustments it is a great way to start an idea on the go.
