I made one for roughly $100 USD from an Arduino, steel rods, some stepper motors, and some 3D printed parts.

Having an existing 3d printer is a bit “draw the rest of the owl” for this, but being able to extend and modify a device like a pen plotter is pretty nice.

You can also pick up used older printers (like the Ender 3) secondhand VERY cheap and convert them.

But wouldn't you need to have the plotter working to draw the rest of that owl? so it seems like a chicken and egg situation as well
