Stevenson screen for mounting on 3/4" electrical conduit

The basket prints as a single piece, rather than individual interconnecting pieces, so it's less likely to come apart in inclement weather - or if a dog runs into the pole. The interior is designed for smaller sensors, up to 35mm x 58mm.  I've been using the inexpensive Xiaomi Aqara sensors for years with good results. I use a zip tie and a 3d printed bracket to hang the sensor. The mounting hole is a bit larger than the ¾" conduit diameter to account for a bit of deformation if you have to hammer the conduit into the ground.  You can use a few wraps of tape to snug it up. There's a 4mm screw hole if you're really feeling fancy.  
The lid is friction fit. The walls are mostly 1.14 mm, which is ideal for printing 2 layer walls at .3mm layer height.
The  I recommend printing the body using organic supports.
I included the fusion360 file if you want to fiddle with the parameters.
