Stevenson screen for RuuviTags?

Any interest in creating/crowdsourcing or something along those lines a Stevenson screen made for RuuviTags?

IMHO a Stevenson screen or something to that effect, would be useful enclosure for RuuviTags used to measure outside temperatures. In my sunlight increased temperatures by about 20 degC compared to nearest FMI meteorological station.

I have that problem in an exposed Ruuvi Tag
