Update v3c adding frames and tetris style.
Tested at 200% for you… but not for me and my quality level, but functional. See in comments, maybe you like.
Update v3b for a new socket with aligned at 30° infill and useless screw for fun.
Update v3 is out ! I have playing with tolerance for stacking good and it's really special but i have need to put 0 for this model, i don't understand but ok, it's fine..
This model is better because you print only you have need, only stack as you want and i like this crazy texture. Many test in progress…
The author remixed this model.
stackable
