Camera Rig for 123D Catch

thingiverse

This is a camera rig for use with Autodesk's 123D Catch software and service. 123D Catch lets you generate a detailed 3D model of an object from a collection of photographs. The rig described here helps you structure the photos for best results. It lets you spin the camera around the object at a constant height and distance, while the object stays still. You can easily move the camera up and down to get top and bottom angles. Instructions The rig requires wooden dowels and some hardware to assemble, but takes about 20 minutes to put together. It breaks down for transport in less than a minute.
