Printed parts with petg, 0.6mm nozzle, 0.5mm layer height, 3 parameter all around, 30% fill. Works well.
I had a 40% infill part lift up and it took huge force to beak it. Lowered infill to 30% after that.
Instead of screw I used a 80mm long piece of threaded M4 rod with couple nuts/washers to spread it open and keep locked.
