It is a breathable box to store objects that need breathability.
To store objects such as flowers, leaves, insects or products that have to dry.
Double wave design provides great strength and stability.
I have printed the model with PLA, 0.4 nozzle and 0.1 layer height for a good finish.
Looking forward to seeing your impressions
The author remixed this model.
It is the same box but I have incorporated a handle to hang from the backpack
