A 3D printable drone frame designed to build a 1200g drone (about 350mm long and wide without propellers). With 300g weight and 100% padding, the frame is quite robust, even with some crashes. The frame can be easily assembled with only 8 40mm long M5 screws and 8 M5 nuts.
Arms are designed for 2312 type motors (with m3 holes 16mm and 19mm apart). Only the legs require support for printing, and a reinforced version is available if you're concerned about crashes. The frame has many holes to facilitate the attachment of various equipment to the drone, but there is also a version without holes in the files if that is preferred.
This drone uses DJI motors and ECS and a custom flight controller based on the multiWii on an Arduino Nano.
