Kerbal Space Program

The T-37 structural tube's top node size is the smallest possible (0.625m) on all length variants making rockets that use it just break apart. All other structural tubes have correct node attach point sizes.

The problem is located in Tube3.cfg:

node_stack_top1 = 0,0,0,0,-1,0,1
    node_stack_bottom1 = 0,-0.2,0,0,1,0,1
    node_stack_top2 = 0,0,0,0,1,0,1
    node_stack_bottom2 = 0,-0.2,0,0,-1,0,1

It should be:

node_stack_top1 = 0,0,0,0,-1,0,3
    node_stack_bottom1 = 0,-0.2,0,0,1,0,3
    node_stack_top2 = 0,0,0,0,1,0,3
    node_stack_bottom2 = 0,-0.2,0,0,-1,0,3

Last digit needs to be 3, not 1.
