Does anyone know of tapered shim or other material to change the angle of ceiling fan blades? - change mount and blade serial

I am a big fan of 5 'cap, we increase the inclination of the slats. Instead you support pucks on the two fixing screws on each sheet for the engine, I believe it with plastic or metal, which is sold maybe 1 / 16 "under a heavy lock on the other 1, 5" apart (1 mm thick, 25mm ), which could be reduced to cover the last sentence.
Suggestions welcome.
