devFrame is a 3D printable, Open Source quadcopter and rover (coming soon) frame design. Supports 300-500 class quadcopter frames in Stretch X, Hybrid X and H configurations, as well as skid steer rovers (coming soon).
Trying really hard to use a standard spec that make sense. Besides 15 and 30mm spacing we need to watch pilot hole diameter. Don't really want to ask people to start drilling a bunch, and if the part is not printed solid you can quickly run out of perimeter plastic around a small hole.
Frame => #6/M3.5 = 4mm Through hole and 2.5mm pilot
Mounts/Large Sensors => #4/M3 = 2.5mm pilot hole
Small Sensors => #2/M2 = 1.5mm pilot
Tiny Sensors => 1mm pilot
