@shuttle1987 I did not found problem when slicing and printing VaccuumAttachment-Body.3mf. It looks the issue may be related to the printer. Is there something wrong with your printer's accuracy if you only print a cube? If there is, please create a ticket and upload the log of the printer. https://wiki.bambulab.com/en/x1/troubleshooting/upload-log
