EarthBox Original (Current Model) Overflow Screen

EarthBox (current model) screen for the oval overflow hole.   Created this to prevent mosquitoes from breeding in the water reservoir.  

I would suggest checking this regularly and spraying water into the screen if it is clogging.  

This part installs from the outside, so you can install it while the EarthBox is in use.  This part is not symmetrical, the tab that is flush with the edge gets installed towards the outside of the box.  Slip the outside edge in place, apply pressure and the inside edge will clip in place.  It is a little tricky due to the location of the outlet hole and you are doing it blind, but once you understand how it goes in it is not very difficult to clip in place.  I have done it on multiple EarthBoxes.

Print with PETG or other UV resistant filaments for outdoor use.  

If you have an early EarthBox with a round hole, check out this model:
