SparkFun Weather Station / Gadget Station - Wind Cups

thingiverse

Replacement Weather cups for the Sparkfun or Gadget Weather meter. This will fit all the derivatives of the same set of instruments. Print is sturdy and tested working. You will need to either salvage the cylindrical magnet, or get hold of a new one; they are common and available online. In the UK multiple companies sell them (such as RS). Print with some form of supports. I print it 'upside down' with the open side (that connects to the weather station) up.
