iPhone 13pro Filter Adapter

prusaprinters

<p>Like may other people with an interest in photography, I have a fairly large collection of round screw-in filters like ND, Polariser etc. These are somewhat of an investment so I wanted a way to use these filters on my iPhone 13pro without an expensive case/cage and dedicated filter system - reuse what I have rather than buy new.</p><p>I printed my adapter on a Longer LK5pro (the .3mf project file is attached). The filament I used is ASA for its UV resilience and moderate flexibility. I used 50% infill, tree supports and 50mm/s speed. Print temperature was 245c and a bed temperature of 64c. All other settings were as per Cura generic ASA profile.&nbsp;</p><p>It works like this. Print the model (with support enabled) and clean-up as usual. Then obtain a 52-58 step up ring which should be a tight fit into the top surface. This will then accept all standard 58mm filters. Should you need to use different sizes of filters, either add additional step up rings (e.g. 58-62mm) or re-model the top surface to be a larger aperture. My design as printed is for an iPhone 13pro with a Spigen Liquid Air Case (amazon.co.uk: <a href="Spigen Liquid Air Case Compatible... https://www.amazon.co.uk/dp/B096HVKHPT?ref=ppx_pop_mob_ap_share"><i>www.amazon.co.uk/dp/B096HVKHPT?ref=ppx_pop_mob_ap_share</i></a>). It may fit other cases but if not a slight re-work of the side grips should sort that out.</p><p>The filter circle is centred across all three lenses rather than the square camera module outline. This ensures that vignetting is avoided.&nbsp;</p><p>&nbsp;</p><figure class="table"><table><tbody><tr><td><p><i>August 1st, 2022 - Update:</i></p><p><i>I have added alternative versions of the filter adapter that are 6.6mm wider which should fit an iPhone 13 Pro Max + case. It has not been test fitted as I don't have the max version of the iPhone so I have also included the original Sketchup file to make any changes you may wish to make a bit easier.</i></p></td></tr></tbody></table></figure>
