An old school rain-gauge.
I designed it to be easily printable with no reworking and only one part needing minimal supports.
The scale is in l/m² or mm/m² (wich is essentially the same :) )
Despite the look on the photo, the cylinder is actually quite transparent and it is easy to see the waterlevel inside.
!! I changed the Cylinder.stl Part !!
!! The old one was the wrong version wich was not printable in vase-mode !!
