Triblader Boomerang with Reinforcing Spine

I wanted to play with different print processes for different parts of my models, so I created this pretty ordinary triblader design with a strengthening spine. The idea was to keep the boomerang pretty low density with little infill and a thin skin, and have a spine-like structure reinforce it.

To be honest, I haven't found any advantage of this design over a regular printed boomerang, but I think it looks cool and cyborg-like when printed, so there you are.

Designed in Onshape: Document Link. How to print the two-part model with different processes will depend on your slicer. Try to align the two parts so they share the same center point.
