I'm very new and love 3d printing but this is really driving twisting my private parts. It started when I tried printing parts to insert into other parts, they would never fit and the inner hole, square or whatever would be warped like in the pic. The pic is supposes to print out coin sizes for coins to fit through.

I have an Ender 3 and using Cura for splicing. I am presently sinking in a sea of bad tests and thinking I'm never going to get a good setting for this.

The settings I have changed (for various other problems with calibrations) are:

Print Temp 210, inner wall width .6, inner wall speed 30, inner wall acc 300, top layers 8, infill overlap percentahe 40, infill overlap .4, top surface layer 1, initial fan speed 25, regular fan speed 2, build plate temp 55, initial layer travel speed 50, skirt brim line width .3


If anyone could give me a hand on what I could possibly do to fix this it would be appreciated.
