iPhone 5s macro lens mount

myminifactory

This design was sparked by lens42's macro lens mount on Shapeways. The designer of that mount tracked down a budget-friendly ($4) lens from surplusshed.com suitable for iPhone macro photography. I sought a mount that would slip over a case, one I could print myself. This version adapts the mount design from my loupe mount to hold a bare lens. Update: A 12mm version was added for Surplus Shed lens L4581, offering higher magnification. Instructions The inner diameter of the lens hole is 12.3mm, which on my printer holds the lens snugly without glue. To adjust any dimensions, download the rsdoc file and use DesignSpark Mechanical (free) to push the hole to any desired dimension. The outer ring features a retaining lip, so you must insert the lens from inside the mount. Easiest is to drop it in from the side, using a pencil eraser to float it horizontally until it settles flat, then push it in from the hole on the mount side. The L4471 lens is plano-convex; its flat side should face towards the phone. An assembled STL is available (slowly rendering), showcasing how it looks when complete. You can print it whole, but you'll end up with a rough bridged surface that might scuff a leather case. Better to print the two separate parts for smooth case-side surfaces, then glue or solvent bond them together using tabs and holes for alignment assistance. Designed for printing at .20 mm layer height and .40mm extrusion width.
