I have a tendency to get really interested in projects for a few months, then move onto another one. One project I tend to do on and off is making things in Blender, a program for 3d designing. Here are some things that I made. Some of them had help from tutorials, some without, and some are modified versions of other people’s designs (such as the phone case).
Playing with rigid body animations (tutorial available at: http://www.youtube.com/watch?v=Ci39zXfG-I4 )
An Iphone 5C phone case I designed for a friend (The blank case and iphone 5c model are both available on Thingiverse)
