This is a housing for a DIY iphone 6 macro lens using the lens component from a cheap LED flashlight. The lens can be easily obtained by removing it from a LED flashlight similar to this one: http://www.aliexpress.com/store/product/Round-Moon-Shape-Light-Aluminium-Alloy-Mini-Flashlight-XML-Cree-Led-Flashlight-Torch-High-Power-Led/1427003_2048795389.html

The lens fits snug into the 3D printed housing and takes pretty decent macro photos as shown in the pictures (a dime was used). The size may need to be adjusted as this one was designed to fit my iphones low profile cover.
