Nice work. There are many elements in this I'd like to see. Sadly, it is clear that I lack your sculpting skills. That won't stop me from enjoying your process.

4" schedule 40 PVC pipe has an inside diameter of 3.998". That changes your math by ~.15 cubic inches per linear foot or 0.1%.

I thought about doing the same some years back but it's much easier to vac-form the wings and fuselage and glue it together form thin lexan sheets... or even cheap plastic sheets.

Um, I still don't see why you just can't turn off 3D printing functionality and just have the electronics control the steppers for the router?
