I tried all the versions, with 6 layers at bottom, top and side, but each time it beaks before being able to break the egg! Nice idea but not working !

I've printed it, great idea. But it doesnt work. Its not moveable in the middle, the "pusher" sticks with the static part.
Printed two times with Ender 3 pro.
Try 1: Layer height 0,2, Walls 5, Temp 215°
Try 2: Layer height 0,12, Walls 6, temp 200°

Both with pla Black (anycubic).
Any Idea?

I'm sorry but print by my prusa MK2 and raise N2 is good. I can remake tolerance for bad setting printers, but tolerance in hinges is quite big.

Good idea, nice design, but the tolerances are not working. Out of all the other print-in-place designs, only this one broke. Also the stls have issues.

I've printed it twice, and it breaks when I try to get it loose. Any tips?

Looks like a great build, however I am confused which file would be best...
