Canon 18-135mm Hood Mount Solar Film Adapter

thingiverse

In anticipation of the August 21st Solar Eclipse, I decided to work on a solar film adapter for the 18-135mm STM lens on my Canon 70D. I want to give credit to two Thingiverse designers for seeding my design: https://www.thingiverse.com/thing:448437 https://www.thingiverse.com/thing:2376354 This design is probably more complicated than is required for the purpose of just holding the solar film in front of the lens, but I wanted to develop my skills with Fusion 360, and it was fun. 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. Do to my novice Fusion 360 skills the STL generated for the main body was full of errors. makeprintable.com fixed it perfectly! NOTE: Not showing the solarfilm in my pictures because I misplaced it somewhere. * 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. video: https://youtu.be/LA4D6swskkc Update: I added the four Fusion 360 design files so that they be modified by anyone. For instance, If you want modify a set of clips and the front cover for thicker filter films or plates. Update 2: Found my solar film.. Spent some time on 8/20/2017 nailing down the setting for tomorrows eclipse. Added some pictures and was able to see today's sun spots. ISO 100, f/32, 1.3s
