Draft model 04 - Size considerations

Originally I wanted to make a 20cm*20cm*20cm box, but I found that I wanted to store some precious relics worthy of being stored in the puzzle box, usually watches, jewellery, letter commemorative photos, etc. Usually the puzzle box is designed to be smaller and more precise for portability, so the size of 10cm*10cm*10cm is finally set. I made a sample model with balsa wood and found that it is very suitable to hold a box of this size by hand. In the process of cracking the decryption box, you will feel more comfortable if you flip or touch it.
