Getting there! A few more tweaks, still getting that z-offset right as the first layer requires babysitting to prevent the backup issue. But the remainder of the print worked without needing intervention (but still watching it just in case). Reduced the print temp down to 210 too as the 230 was just making a stringy mess. I've also made the print quality/layers finer.
Now to try to print a more rounded version of the correct dimensions.
