I printed one out last night PETG, . 0.2mm layers 235 Nozzle. 0 Bed heat ( don't have one ) Everything else is default simplify 3D PLA Settings. Didn't change a thing. 0.05, 0.1, 0.15 wont spin. The rest spin fine. The 0.2mm took just a slight amount of force to free it up. Mine looks like a slicer issue to me, when I viewed it those smaller tolerance ones were touching in the slicer anyway..
