I’ve been working on a 3D printed drone project for the last 5 or 6 months, and I’ve finally got it finished enough to publish a nice build log. Check it out on Instructables! http://goo.gl/wD0f3K (I’m also entered in their flying things design contest and you can vote for my project if you like it)
I designed 12 different 3D printed parts to mount motors and electronics to carbon fiber arrow shafts. All of the plastic to carbon interfaces float on rubber o-rings to reduce vibration transfer.
I also designed a 3D printed mold to create my own silicone vibration isolators.
The isolators mount in a triangle and are angled in so that each one is 90 degrees apart from the other two, like the corner of a cube. The idea is to absorb vibration equally in all directions. This reduces the amount of background noise that the accelerometers and gyros see and helps the craft fly more stable and controlled.
It’s a work in progress, and I’ll continue to add to it and change it, but I wanted to share it with you in case anybody else wants to build one. The design files and step by step instructions are posted on Instructables for download.
