Summary

This is an adapter to space T-style props away from the motor a little. (2mm)
I found that Hobbyking 8x5.5 Vinyl props didn't quite clear my Storm drone's motors, and if done up firm, the props bowed up at the end.
Two options with 4mm central hole, and 3mm (small hole) which can then be gently reamed to fit shaft better.
This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/iL8vxMfkb6w
