Nozzle hitting print at certain layer

Hi guys,

I’m having an issue with a print being hit by the nozzle at a certain layer. If I print just 1 model the print is fine but when doing multiples they are always failing. I’ve tried it on 3 different printers (H2S, H2C, P2S) all getting same problem.

Picture attached of the area where the issues starts to happen.

Any ideas?
