The CAD files for the test print are done! I listed the "full concept" print as wing.scad in my github, and the actual print file (which is less likely to fail due to lack of support) as wingPrint.scad*. I'm currently waiting for Slic3r to finish slicing so I can start the print and head home.

In the meantime, I've been extracting a vital component of the finished product -- bike wheel bearings. Since I don't want to fork over upwards of $20 or wait two weeks for American Science and Surplus to ship, I'm using the bearings and cones recovered from a bike wheel and adding the cups as an integrated part of the print. 

The grease from a bike wheel (especially a recycled wheel like the one that I'm using) is a little too thick, so I used some dish soap and hot water to soak it off, and I'll add a different lubricant in the morning.

*You'll also need the *.dxf files listed on my github in order to compile and export these files.
