I remixed the lid for the Combined Desiccant Cup / Hygrometer Mount for Filament Dry Box. The original lid looked nice in the preview on the slicer, but when printed the design was just overhang pattern and didn't look so nice. I just imported the model into Tinkercad and deleted the top pattern so it's one flat surface. I also edited out the additional lip, so the lid sits all the way down into the container lid instead of raised up a bit. You can still grab it and pull it out of the box if needed or push it up from the bottom.

Printed on Creality K1 Max with .20mm setting. I did use tree support around the locking slot on the inside, but it's so thin it may not be necessary.

(Note this is just the lid. Please see the original design linked above for the cup since I made no changes there)
