Stretched wing parts of 3DR Simple.
Additional length is parametric. Open openscad script and change the value of add_length whatever you want and recompile it. Note that johnSL's original stl files should be at the same directory where scad script is, and I had to change original top wing's name as 'Wing Top.STL' to avoid conflict with bottom one.
Attached stl files are 26mm longer than original ones to get 200mm diameter build space. Here is a simple math. Original 3DR Simple is designed for 170mm diameter base. So the printer should be larger 15mm in radius. It's equal to 15x2xsqrt(3)=52mm in circumferential direction.
