Description
This is a parametric lid for trash cans whose opening resembles a rectangle.
I use it as a lid to my bio-degradable waste to prevent plastic from accidentally falling in there from nearby plastic recycling bin.
Designing / Printing
You will need to fill the following parameters to make it fit your trash can:

I measured the lid_radius with these fillet swatches

I did it by putting the round end of a fillet swatch to the inner corner of my trash can like below

Tips:
You can print either a solid version (see the white lid in the pictures), or a porous one.
A porous lid will act as a barrier for e.g. material falling into the bin, but it will let moisture evaporate. This will let bio-waste last longer before mold grows.
To make a porous lid (see the black lid in the pictures), I set perimeters to 12, and top and bottom layers to 0. I printed out of PLA, 20 % honeycomb infill, 0,25mm speed profile on MK4S 0.4 mm HF nozzle.
