This page is about the 3D-printed quadcopter frames I designed in the years 2016, 2017, and 2018. I made several versions of them using different sizes of carbon fiber tubes. I also tried to improve the durability by strengthening parts that broke frequently and weakening other parts that did not need to be that durable to save weight. I also made several adapters and mounts for different things, such as FPV cameras, antennas, and LEDs that screw onto the frame for customization. The carbon fiber tubes are glued into the 3D printed parts using epoxy or CA glue, and the rest of the 3D printed parts are screwed together with M3 screws and 3D printed standoffs to form the frame. 

This was an interesting project to work on to learn more about mechanical CAD design for 3D printing, as well as prototyping, testing, and optimizing. Keep in mind that my 3D-printed quadcopter frames are still a lot weaker than the normal carbon fiber plate-based FPV quadcopter frames you can buy. Therefore, my design is not suited for beginner pilots or anyone that might crash. However, if you are an experienced pilot that likes 3D printing and wants a unique long-range FPV frame for example, this can be an alternative.
