This is the right wing of a rubber band powered, peanut scale model airplane designed by Walt Mooney called Mordecai Murphy's Dart.
The goal is to recreate the model in way that allows for most, if not all, of the parts to be 3D printed and flyable using current micro RC electronics.
Where possible, parts have been designed to negate the need for rafts or support material.
The first part of this work in progress is the right (and left, if mirrored) wing.
The ribs of the wing are about 0.56mm thick - which is about the thinnest wall I've been able to get out of my Makerbot Replicator.
Layer height: 0.2mm
Extra shells: 0
Raft: no raft or support material
It's worth noting that the airfoil on this wing is prone to funky stall behavior. The original design uses a more symmetrical airfoil. But the flat bottom airfoil prints really well, so maybe it's worth it?
