It is strong enough to support the weight of the inert hollow body upside down and sideways. I would recommend glue for heavy handling. This set will complete your existing project. Just paint them to taste and screw it on. This is a one piece print. Mortar body and fuze not included Usually ships within 1 to 2 weeks. Hand made to order. These are printed in high-quality PLA, which is bio-degradable. These are senstive to high-heat and high-moisture. All of these products are proudly made in America.. by me, MakerSteve. They are hand finished to the best quality I can create with a 3D Printer. They will come with some imperfection due to the 3D printing and painting process but you'll like 'em, everyone does.
