R.E.P.O. Robot V2

Here's the V2 of my R.E.P.O. Robot. You can open the mouth of this one, in the 3mf you'll find a small 2 layers rectangle, u need to simply cut it with some scissors the lenght u want, and superglue it in place making the flexible hinge. it's curved so if u make it more round it will flex less but the head will be more centered. i'll also make a V3 cause this one feels too complicated and not reliable. if u want to give it a try and give me a feedback i'ld be grateful.
