Air vent cover for well 70mm with locking ring

I used the scad from https://www.thingiverse.com/thing:3091169 t make it fit the 70mm pipe/vent on the well. I also made locking ring 75mm with a coned inside to lock it in place.
Thanks FunLife for the original part!

*added the 25cm mesh for insect/dirt protection.
Print Z at 0,4 as the part or 4 layers (0,8).
Top/bottom layer set to 0.

Use a gluegun or 3d-pen to put it in place.
