<h3> 3D Print your Macro Photography</h3> <h3>In Brief</h3> <p>This adaptor allows you to take macro photographs with Canon EF or EFS lenses. It was designed with kit zooms in mind. All examples use a kit 18-55mm and 25:250 kit zoom.</p> <h3>The Series</h3> <p>The adaptor is part of a collection of 3D printed macro photography tools:</p> <ul> <li>Reverse lens adaptor.

This adaptor reverses the lens's direction, which gives it magnification and attaches it to another lens that acts as an extension tube that increases the magnification further. With two Canon kit zooms, I got up to 14X magnification. Generally, the quality is higher than the single reverse lens, but the quality falls off at the extreme end.</p> <h3> How to use it</h3> <p>You will need two lenses of different focal lengths.</p> <ol> <li>Mount the longer lens on your camera.</li> <li>Set its focus to infinity and the aperture wide open</li> <li>Screw the adaptor into where the filter would normally go.</li> <li>Screw the second shorter lens onto the other side of the adaptor so that the lenses face each other</li> <li><p>Move the camera back and forward, or use the front lens to focus A detailed <a href="https://www.instructables.com/3D-Print-Your-Macro-Photography-part-3-the-Coupled/">Instructable</a> is available.<br/> .</p> <p>### Reverse Lens Hood and Diffuser</p> <p>The reverse lens hood isn't essential but stops stray light from entering the lens, protects the delicate rear element, allows you to attach filters and the diffuser. You can also add reflective material that helps light the subject.</p> <p>The diffuser mounts onto the reversed lens hood. It's designed to deflect light from above and behind the lens onto the subject. It's most valuable when used with the internal flash.</p> <p>### Subjects, Example Images above, (Left to Right)</p> </li> <li><p>Sourveneer spoon (50mm paired with 250mm lens).</p> </li> <li>Sourveneer spoon (18mm paired with 250mm lens).</li> <li>Opal Chip from Lightning Ridge Australia (18mm paired with 250mm lens).</li> <li>Sharp pencil lead (18mm paired with 250mm lens).</li> <li>PLA at .2mm (18mm paired with 250mm lens).</li> <li>Inkjet-printed squares (18mm paired with 250mm lens).</li> <li>Reference for actual size lead pencil and squares.<h3>Print Settings</h3> </li> </ol> <p><strong>Printer Brand:</strong></p> <p>Prusa</p> <p><p class="detail-setting printer"><strong>Printer: </strong> <div><p>i3 MK3 MMU 2</p></div><strong>Rafts:</strong></p> <p>No</p> <p><p class="detail-setting supports"><strong>Supports: </strong> <div><p>No</p></div><strong>Resolution:</strong></p> <p>100</p> <p><p class="detail-setting infill"><strong>Infill: </strong> <div><p>20</p></div><br/> <strong>Filament:</strong><br/> [</p> <h3> 3DFillies PLA but prefferably PETG ](http://www.amazon.com/s?url=search-alias&amp;field-keywords=3DFillies+PLA+but+prefferably+PETG&amp;tag=thingiverse09-20) black, blue, clear <br/> <p class="detail-setting notes"><strong>Notes: </strong> </p><div><p>Clean threads up carefully.
