Updated and simper version in http://www.thingiverse.com/thing:662297
The three parts assemble on the ring as shown in the images. Once assembled you should be able to use the zoom gear to control zoom.
Note that the base is pressing on the "macro" button, so make sure that the zoom control is in the mode you want (usually "electric zoom").
These parts were designed on AutoDesk Inventor Fusion (Mac) and printed on PP3DP Up! printer.
