Why won't this attach?

[Leicontis]

I\'m working on some tiny radial decouplers, sort of a 'my first mod' attempt. Unfortunately, I can\'t get them to actually attach. Could anybody point me in the direction of where I\'ve screwed up here?

Point (0, 0, 0) you\'ve specified as \'node_attach\' is well inside the collision mesh. Decoupler collides with a surface instead of attaching to it.

5 cm is the maximum X-coordinate in .DAE file. I prefer to leave some space between parts\' colliders, so I changed attachment point to

node_attach = 0.06, 0.0, 0.0, 1.0, 0.0, 0.0

and it worked.
