super easy print. it doesn't take much filament. works pretty well right of the build plate. every once and awhile they need a little working to get them butter smooth. not sure if I like the joints or not. on ine hand if they do pop loose you can snap them back together easy. on the other hand, I like them to be more secure. I'll update after the kids play with them. How durable they really are. over all a pretty good print.
