Systems and methods for joining node and tube structures

An apparatus, comprising:

• an additively manufactured first node;
• an additively manufactured second node;
• a tube;
• an interconnect connecting the tube to the first and the second nodes, wherein
• the interconnect comprises a base and a shaft extending from the base;
• and
• a spacer structure arranged between the first node, the second node, the tube, and the interconnect, wherein the spacer structure is configured to entirely separate one or more of the first node and the second node from one or more of the tube and the interconnect by a first separation distance, and wherein the spacer structure is configured to entirely separate the tube from the interconnect by a second separation distance, the second separation distance being smaller than the first separation distance.
