iPhone 5 Microscope Adapter

thingiverse

To simplify microscope cell counting, utilize still images instead of real-time viewing; however, expensive microscope cameras can be a constraint. As an alternative, create an iPhone 5 microscope adapter using laser-cut acrylic and double-sided tape. Although not perfect, this solution works well. The required rubber feet are McMaster part #95495K68, while the acrylic is cut from 1/4" and 1/8" nominal thickness sheets. Adhesive sheets like 3M 468MP, Thermoweb Peel-n-Stick or double sided tape can be used for layering. To build this adapter, laminate a 1/4" thick acrylic sheet and another 1/8" one with double-sided tape. Customize the eyepiece rings in the CAD file according to your microscope's ocular diameter. Cut out the pieces based on the CAD file instructions, ensuring the tape side is facing down during laser cutting. The layers should be in this order from the microscope side: 1/4", 1/4", 1/4", 1/4", 1/4", and 1/8". After cutting out, remove the backing from the outermost 1/8" piece's tape and scrape off the tape where it would touch the phone. Attach the rubber feet on the designated rounded areas, then peel off the rest of the backing and assemble.
