I modified my previous “small box printable in one piece”.
Previous locking system was not good for shape nor for printing. So I modified the model into using magnet for closure. The size of magnet used is 6mm diameter and 2mm thickness.
I also made the size of box smaller as 90% of original one.
I used support on build plate only.
I tried PLA, PETG and TPU-95A, and the result was good.
The author remixed this model.
