Something I've been meaning to get to for a while. And also a request. This one has been designed to print with a 0.4mm nozzle as opposed to a 0.3mm like many of the others. And has been extended out to 105mm as to better accommodate 65mm props. I've included the F3D if any wish to tweek. I recommend a thinner layer height such as 0.1mm, and like the other bare bones frames is designed to be printed upside down and the motors mounted to the flat side.
