My kits for each light consist of one clip and the stainless-steel attachment hardware.  I print them in PETG which is a strong and flexible material that has good temperature characteristics and withstands the environment well.  PETG is what is used to make drinking water bottles.  The clip design has been out for a few years but I just started making them a year ago.  I recently made a minor modification to reinforce the tip by adding some additional material so my clips are a second generation over the clips that other members made in the past.  The clip replicates the original tip of the light so installation/removal procedures would be the same.  The pictures below show the repair sequence.
