I think it could be the printer missing steps, but it could also be the object becoming a bit loose and wiggling? Or a defect in the model or slicer-bug?
First, in Cura (or other slicer) always check the model in Layer-View, to see if this defect is there or not.
Check if the printer head moves smooth in X- and Y-direction. Movement could be blocked by debris, or lack of lubrication.
Then, while printing, keep watching closely what happens. You should be able to see the difference between wiggling and skipping.
While printing, you could also push the head, to see how hard it is to get it to miss steps. If it is very hard to do, this is unlikely to be the problem. If it misses steps at the first touch of your finger, it could very well be the problem.
Although I don't know your filament, for such small objects, 210°C looks a bit hot for PLA-materials. I would normally do 195...200°C for such models, which should give less stringing. But that could depend on printer and material. Try on the fly to change temp in steps of 5°C, and see what happens.
Is there anything to lubricate rather than the z axis rod?
