Canon EF mount for macro bellows
prusaprinters
<p>Recently I've designed <a href="https://www.printables.com/pl/model/250547-macro-photography-accessories-focusing-rail-and-be">bellows for macro photography</a> using 3d printed parts, 200 mm of 2020 v-slot profile, some hardware and a EF mount scavenged from a broken lens. This design is basically a copy of the original brass mount with a slight increase in thickness to allow the use of counterbore M2 bolts. </p><figure class="image"><img src="https://media.printables.com/media/prints/252207/rich_content/c9073e11-8350-4588-81b8-2e3d87d44f8c/comparison.jpg#%7B%22uuid%22%3A%229d3a09b7-f645-4cec-89ae-40d9a501ea92%22%2C%22w%22%3A1500%2C%22h%22%3A1000%7D"></figure><p><strong>Required hardware:</strong></p><p>4x M2x10 bolts</p><p><strong>Guidlines for printing:</strong></p><p>On my Prusa I3 MK3s with 0.6 mm nozzle I've managed to get it printed without supports with 0.1 mm layer height in PETG.</p><p>I recommend to use dark colored filament to avoid reflections.</p><p> </p><figure class="image"><img src="https://media.printables.com/media/prints/252207/rich_content/ec284ed9-3959-43dd-9678-d63395f6a248/mounted.jpg#%7B%22uuid%22%3A%2265783f46-a348-4f10-8f16-6f3f3162b82e%22%2C%22w%22%3A1200%2C%22h%22%3A1501%7D"></figure>
