Multi-Material hinged Box

This is an experiment i've been working on.. It is about combining flexible and non-flexible material in one print.
Feel free to play around with it as well ;-)

it has been designed in a way that the two materials are interlocking into each other to improve the bond between the material.

I've printed this on a standard Prusa MK3 without MMU by using this method: https://schlosshan.eu/blog/2019/03/02/prusa-i3-mk3-real-multicolour-prints-without-mmu/

feedback and comments are welcome ;-)
