Hello I am relatively new to 3d print but i am using Cura to slice my models from sketchup to print on my new anycubic mega x printer. I am trying to print smaller objects of higher precision to coincide with real-world parts, so I am most concerned with settings that will make my 3d output as close to the original sketchup as possible. In my first example, i am printing a 26.0 mm disc with an inset disk at 22mm. Once printed, the outer is 26.0 and the inner is at 21.4mm measured with digital micrometer. THere are many settings which might effect this, should I adjust inner hole expansion with a negative value? I really am most concerned with getting output that approximates the sketchup dimensions. I don't expect it to be perfect, due to warping, shrinkage, expansion, etc., but just to get as close as reasonably possible so that real world parts will mate with what I print! Thank you Doug
