Instructions
The laser cutter ponoko used to produce this left small "pixelated" indentations along all curves (see image). No big deal, except the vanes need to slide unimpeded along the inner ring, so it had to be sanded and polished manually for the motor to work.
The screw holes are superflous as the acrylic does not really seal well by just screwing the three layers together. I had to glue them with generous amount of Faller Expert Plastic Cement anyway.
I also sanded the sides of the rotor slightly to decrease friction.
For propellant I used a can of common Dust Off.
