Key Chest from game Levelhead (storage box)

MY PRINTING: https://www.youtube.com/watch?v=xjTUHM654vk This is the Key Chest , a storage box in the game Levelhead.It can hold items and enemies in the game, however only items is allowed in real life.Comparing the mechanism, I did some design changes in order for the Key Chest be more useful in real life in my oppinion.Regarding 3D print configuration:no support is requiredrecommend printing the LID upside-down0.2 layer height was enough for me (see video)After printing, a white paper for the eye is required. Also, some glue too (be careful).Excluding LID, box's internal dimensions: 71mm x 51mm x 63mm (W x D x H)
