In practice Ukrainians have long moved to custom built drones for pretty much everything.

Picking up 3D printers that don't spy on you, modding them or even building custom ones is much easier than designing and building millions of custom drones, so I am sure they solved this long ago.

Like, really - a FDM printer is just a MCU board with a bunch of stepper drivers, a power supply, some frame, motors, thermistors & heating elements.
