Cereal Box "Kichly" insert for round Hygrometer

Since I didnt find any insert for the lid of the "Kichly" 4l cereal boxes, i made my own for holding a round hygrometer. It fits with both versions of the "Kichly"-Boxes "Kichly"-Boxes: https://www.amazon.de/dp/B0BL379HYX?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1 Just print it as it is, in the material you want. First snap the hygrometer in the insert, than press it in the lid. The battery is still accessible afterwards.
