Here's a dry test fit of the forward and rear nose cone supports. The lower support has a slot for the shock cord lug attachment.
The shock cord "lug" is slid through the slot and glued in place.
If you ever build one of these kits, be careful here. I broke the centering ring support on the engine mount side when pushing the low lug in place.
The laser cut pieces are thin and delicate.
The shock cord is tied on before gluing the support into the nose cone side. It'd be hard to tie it on after the support is glued in.
