0.67x generic wide angle macro lens dummy

Creating a project with a 0.67x wide angle generic lens? You can use this dummy file to help you position and create your item in your software package. Please note the 'glass' areas are not accurate and only show where the glass is situated, as I can't measure the actual size.
Sketchup and STL files included. Hopefully the STL's are now suitable for printing.
Will add the middle screw thread part at a later date.
