Customizable Rocket Nose Cone Coupler

A coupler that may be used to join a model rocket nose cone to the main body tube. This is especially useful for a split halves nose cone as in the Eggloft Egg Rocket Nose Cone here: http://www.thingiverse.com/thing:2228825

The top setback portion is available area to tape the shoulder of the nose cone to this coupler. This length in combination with the length of the nose cone shoulder should be enough to accommodate the width of the tape that will be used.

The hole in the bottom allows an eyelet to be screwed in to the coupler for tying to the shock cord.
