<p>In anticipation of the August 21st, 2017 Solar Eclipse, I decided to work on a solar film adapter for the 18-135mm STM lens on my Canon 70D.</p><p>I want to give credit to two Thingiverse designers for seeding my design: <a href="https://www.thingiverse.com/thing:448437">https://www.thingiverse.com/thing:448437</a> <a href="https://www.thingiverse.com/thing:2376354">https://www.thingiverse.com/thing:2376354</a></p><p>This design is probably more complicated than required for just holding the solar film in front of the lens, but I wanted to develop my skills with Fusion 360, and it was fun.</p><p>The mount utilizes the hood mounting flanges, and friction fits in place. It comes off/on easily with one hand quickly and stays in place.</p><p>Due to my novice Fusion 360 skills (2017), the STL generated for the main body was full of errors. makeprintable.com fixed it perfectly!</p><p>NOTE: Not showing the solar film in my pictures because I misplaced it somewhere.</p><ul><li>Print the body, flange side down. I placed 2mm supports inside the cylinder to support the internal overhangs of the hood mount engagement thread things.</li></ul><figure class="media"><oembed url="https://youtu.be/LA4D6swskkc"></oembed></figure><p>Update:</p><p>I added the four STEP Files so that they be modified. For instance, If you want modify a set of clips for the front cover. You may need to modify the clips depending on the thickness of the film or plates being used.</p><p>Update 2: I found my solar film. Spent some time on 8/20/2017 nailing down the setting for tomorrow's eclipse. Added some pictures and was able to see today's sun spots.</p><p>ISO 100, f/32, 1.3s</p><h3>Print Settings</h3><p><strong>Printer Brand:</strong></p><p>Wanhao</p><p><strong>Printer:&nbsp;</strong></p><p><a href="http://amzn.to/2DqRItw">Wanhao Duplicator i3 Plus</a></p><p><strong>Rafts:</strong></p><p>No</p><p><strong>Supports:&nbsp;</strong></p><p>Yes</p><p><strong>Resolution:</strong></p><p>0.2</p><p><strong>Infill:&nbsp;</strong></p><p>50-100</p><p><strong>Notes:</strong></p><p>Flexion Extruder</p><p>Inland Black PLA</p><p>Slicer Simplify3D</p><h3>How I Designed This</h3><p>Used SolidWorks file from <a href="https://www.thingiverse.com/thing:448437">https://www.thingiverse.com/thing:448437</a></p><ul><li>Removed the hood.</li><li>Imported it into Fusion 360</li><li>modified in Fusion 360<ul><li>added knurling and extra internal flange to prevent back-light entry from the rear when installed on the lens.</li></ul></li></ul><p>Visually recreated the parts in <a href="https://www.thingiverse.com/thing:2376354">https://www.thingiverse.com/thing:2376354</a> to fit my project.</p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p><p>Category: Camera</p>
