This is a project I did for the office at Design that Matters. We have two cameras and one webcam that we move around on mounts all of the time. We wanted to make a quick release system that could easily attach our cameras to the tripod, tv and other hot-spots around the office. Quick release attachments do exist already, but 1. they're fancy and expensive, made for professionals, and 2. they typically only exist for tripods. We wanted something we could crank out of the 3D printer and use everywhere.
The underlying tutorial for this post is how to add functionality to a 3D printed object.
Maybe someday I'll write a full post ranting about how sad I get looking through Thingiverse at all of the desk toys and interesting ways to prop your phone up. Any year now, 3D printing and desktop manufacturing is going to revolutionize consumerism! It's frustratingly hard to be an individual in a world where everything you own, at least 1 million people have the same exact thing. I can't wait for the rise of mass tinkering and customization. When everyone, has the capability to make decisions about their individual needs.
The trick is getting a good press-fit sized hole for your 3D printer, every machine is minutely different. Test out your machine by printing this calibration block. Or, if you have different sized locking nuts, try making your own! I used calipers to measure the actual dimension of the nut. I used the true measurement in the center then added two variations on each side +/- .25mm and +/-.5mm.
Test out the locking nut in each hole to see which fits the best. ideally you want a tight press-fit to avoid using glue. Use the best measurement as you design from there.
