My plan is to make both rotors one fused piece. 3D printed resins are on the brittle side (although I'm not sure the exact stuff IWM has printed) and assembling them is a trial so I hope it's a good alternative to two separate ones.
I think this thing is already looking like seven pieces which sounds like a lot for a pretty small VTOL. (Main body, left wing, right wing, left launcher, right launcher, rotors, and tail.)
And here's the revised rotor piece:
