Hi can you let me know how they printed incorrectly?
Sometimes depending on which slicer software you use it may not bring the model in strait. I used Cura which has an option to center and make sure the model is flat to the bed. You can look at the model from the underside to make sure it's flat on.
Otherwise it may not print cleanly or may even detach from the bed while printing.
Or if it was the print settings you used, could you post them.
If it helps I can send just the arms so you can try more prints without running the full model each time?
(I'm not at my pc to upload them right now so I can do it later today for you)
