CAN LID

I use it for my dog food can, which my dog can not eat at once, so I need to save rest for next time in refrigerator. Smell of this can would evaporate to all refrigerator and add this smell to some vegetables, fruits butter and so. So this lid can close it more less hermetically.
Printed from flexible TPU 32D.
Model I made in OPENSCAD as parametric model. You do not need to know how to work in OPENSCAD.
Just follow this:
Download OPENSCAD: https://openscad.org/

Install it and open model file: "can_lid.scad". At the beginning there is variable:
can_diameter=74;
Change value in mm according diameter of your can. Then render model (press F6). Then export to STL (press F7). That is all.
I printed it with many bottom and top layers, so there is no infill.
