3D scranner

Ever since i got my 3D print i have always wanted to make a 3D scanner. I have got a Xbox kinect sensor and have used it to scan things in to the computer but it can only really do large objects, rooms or people. I have also used 123D Catch but it is very hard to get a good scan with just images and without a turntable with set angles. The scanner that I need uses a laser to show the side of the object. This has different problems over the other methods but may work for what I need.
