Got an extra Fireman Sam helicopter from my next door neighbour and want to give it to my nephew but one of the blades was missing. This should be a direct replacement and just snaps in. I printed all three so that they look the same.
Printed at 100% infill to make them as robust as possible. Made the resolution 0.1 to try and print the little nubs properly although they seemed to print okay at 0.2 as well.
