Syma S107 Helicopter Top Blades

I made these blades just to test my replicating ability. The blade is very close to the actual size but of course, the weight is off. I made them with PLA but I imagine there is a more lightweight material that could be better.

The roughness in the blades are from the printer and my lack of wanting to clean them up.

The lowers are just mirrors of the uppers.
