This is a multi-pieces miniature ideal for wargames. The part need to be glue. If you are confortabled with printing multiple pieces at once, you can use the Tray file that include all the parts. I include 2 versions of the base and the shield, one have holes representing battle damages, the other without the holes. The canon itself have a version with 4 small wings on the base for more stability. You can remove the wings after the print with a cuter. You should be able to print all the piece without additional support.
