iPhone 4 Macro Lens modified

This is derived from http://www.thingiverse.com/thing:19936 by Andrew Barton. I made one of these and thought it was a brilliant idea but I wasn't happy with the design so I made some improvements to suit my needs. The lens is a push fit and needs no glue. The adapter has been resized to fit over my iPhone4S case so I don't have to remove it to use the macro. The top edge was thin and fragile over the flash hole. Since the flash overpowers close-up shots I never use it, so I removed the extra hole. Now that the lens doesn't need glue, the hole in the upper layer is redundant. I have closed it off and added a small bump to grip the the front glass. This can be manoeuvred over the top edge of the case. I made the rounded corners much smaller to overcome the nasty overhangs that distorted the first few layers. I am a complete OpenSCAD noob so please excuse my poor code but I decided to be brave and share it since it did use it and it did actually work! Instructions Follow Andrew's original instructions for obtaining the lens from Surplus Shed. Delivery to the UK was only $4 which was a very pleasant surprise. Print at a fine resolution using the Cooling options available to you. This is a small thing and will probably overheat if you don't. Clean your lens well and hold it with the cloth as you press it, convex side first, into the hole in the adapter. If your lens really won't fit into the hole, use OpenSCAD to increase the lens radius variable from 6.1 to 6.15 and try another print. Don't risk breaking the lens!
