Edit added a new smaller knurled spinner ideal for goggles :-)
Thanks to aubenc for knurl surface library http://www.thingiverse.com/thing:32122

I am always loosing my SMA spanner so I have come up with these.

Two SMA spinners to help you attach or tighten your FPV antennas
Or any SMA antennas if you have large fingers or wear gloves
May also be of use for arthritis sufferers who like FPV
Smaller one is more suited to goggle mounted antennas

PLEASE DON'T OVER-TIGHTEN AND BREAK YOUR ANTENNAS !!

Print the one you need carefully slide it over your SMA connector
These are a tight sliding fit so the do not fall off,please dont force them on and break your antenas
PLEASE DO NOT OVER-TIGHTEN YOUR ANTENNAS !!!!!
Happy flying :-)
