Thanks Bruce. Yes, the intent with these parts was to use them as printed, with addition of inserted threads. But, this is the first time I¡¯ve tried such thick and dense prints and both had serious warping on the bottom. PLA+ seems to be more likely to do this on my printers. I¡¯m learning, I hope and the next attempts may be better. Learning is something I love to do, so I decided to try to machine the parts into something useful. I think it will work.?
