Alright, found a 3D model of the Ikea 365+ 10.6L container that everyone uses as filament box. However, it did not have a modeled lid, wich was exactly what I wanted.
My measurements are close, BUT not super precise, so don't complaint when I share the model, when reality is you should NEVER design something tightfitting for plastic containers like this, without a real life reference.
Now that I have the lid, I can model what I want to do to turn this into a rael filament box.
