This clip acts as an adapter to hold a PET bottle upright inside a flimsy backpack. It uses any existing loop or clip for a hydration pouch inside the backpack.
Use 2mm paracord to create the loop, tying a knot at each end to prevent it from sliding out of the holes.
The clip is designed for bottles with a 25-27mm neck section.
Prints well in PET-G, but should work with most materials. With the cord, this robust print (3 perimeters) weighs 4g.
