<p>A variant of <a href="https://www.printables.com/social/25723-thenickdude">TheNickDude's</a> awesome <a href="https://www.printables.com/model/143756-canon-efef-s-lens-mount">Canon EF/EF-S Lens Mount</a>. This variant has 5 screw holes that can be used for attaching adapters with hard-to-print geometries, like 160mm long microscope objective adapters.</p><p>I recommend printing it in black PLA with at least 4 perimeters to avoid light bleeding through the plastic, which will cause blurry images.<br><br>TheNickDude recommends printing his piece at 0.1mm layer height, but since I've added a lot of feature-less layers I recommend only doing that at the top part (the locking mechanism itself) and printing the rest at 0.2mm or more. I've uploaded a .3mf file with adaptive layer height as an example.</p><p>I've also added modifyable STEP and F3D files for designing your own adapters.</p><p>Example adapter: <a href="https://www.printables.com/model/218910-microscope-objective-adapter">Microscope Objective Adapter</a></p>
