help to print side holes round, but not elliptic

[c310]

i have designed and trying to print delta feet and can not manage round side holes. ones on the picture seems to be round, but are ovals in reality. AND printed part was scaled to 110% on Z axis, making holes more round, but breaking vertical part sizing... dutetWiFi + slic3r PE

I haven't got a definite solution that will work at the slicer level as it looks like you already have a small layer height, but one way that works for me is to drill the holes out after they have been printed.

Another solution may be to add a little cut in the top and bottom of the circle where it goes flat. Your holes wouldn't be perfect circles but they should let you fit a bolt through.

This guy has an excellent tutorial for modeling holes!
