Insulating lid for filament baking

If you have a large heated bed and want to bake moisture out of your filament, this should do the trick!

I printed this with a brim, the lid surface was made specifically to mitigate film stress so bed adhesion shouldn't be an issue.

Low infill here is important, 10% allows for decent filament bridging and captures a lot of air, making for a decent R value insulator. With my heated bed set to 80 C I measured the air inside the lid to be 72 C (after an hour).
