@west under a proper torque spec it might be okay. I have accidentally cracked a few of these when tightening by hand. We should be able to easily modify this to be stronger if need be

While slicing we noticed there is an overhang which prints in mid air, and a thin wall that is not easily registered in cura, I had to drop nozzle diameter to 0.25 for it to recognize it.

@enugent i was able to print these no problem using .5mm nozzle diameter. I am not sure which overhang that prints in mid air you are talking about. Can you clarify?
