When my brother came to me with a proposition to make a lens hood for his old Yashica I honestly wasn't sure how well the Makerbot would be able to pull off a task that required such fine detail: I needed something that would twist and lock onto three flanges. After just a few design iterations though, I could see that it was going to work.
For me what was so awesome was that the Makerbot allowed a very natural and intuitive design process/flow. I quickly mocked up a rough design and printed it out. This allowed me to see where problems were going to come up. I thickened it in areas and adjusted some dimensions and printed another. I went through another two iterations to finally come to the perfect design. This all happened within five hours of my brother even suggesting the idea while still having time to watch a full movie and eat dinner.
Definitely one of the most satisfying designs/things I've made especially considering this is something that is very hard to buy these days.
Thank you Makerbot!
Paint (should probably either print with black or paint it black)
