Pocket Siren updated! Answered

I've just updated my popular Pocket Siren instructable with improved cutting files.

The changes I have made are:
  • Turbine blades widened at the base - massive amounts of use revealed a weakness in the base of the first version.
  • Turbines engraved in the laser - rather than sanding them down, I placed a circle of engraving over the blades (watch your laser settings, make sure it's set to engrave).
  • The axle is now also acrylic, not wooden, but you don't have to buy any acrylic rod!
  • Lanyard/key-chain loop added to the central layer.
