This hexagonal box was inspired in the ones that appear in the animated series Miraculous Ladybug.
Some adjustments were made in order to make it more suitable to be printed in 3D, and you can print it in one session!
PLA is recommended. This object is "print in place" and doesn't needs any support, just a minimum of 2 shells and 30% infill in order for the hinge and lock to work without breaking.
After the printing process has finished, let the piece cool down for a few minutes.
Detach one side first and slowly move it upwards. The hinge should work and allow you to close the box. Then, you can safely remove the other side.
