The GG Modifier is a printed plastic Grigri attachment with a cord loop. Mine is 70 mm. long, 19 mm. wide, 13 mm. high, and weighs 6 g.

• Prototype #1 is printed from soft black TPU 90A. It is 47 mm. long, 19 mm. wide, 10 mm. high, and weighs 3 g.
  
• Prototype #2 is printed from soft turquoise TPU 90A.It is 51 mm. long, 19 mm. wide, 10 mm. high, and weighs 4 g. It has the pink polypropylene cord used on the original production models.
  
• Prototype #3 is printed from soft turquoise TPU 90A.It is 80 mm. long, 19 mm. wide, 10 mm. high, and weighs 6 g. It has the black nylon cord used on newer production models.
  
• Prototype #4 is printed from hard black PLA. It is 70 mm. long, 19 mm. wide, 13 mm. high, and weighs 5 g. Its cord attachment bridge was broken during destructive pull testing.
  

Prototypes #1 and #2 have no markings. Prototypes #3 and #4 have "BCT" printed into one side.

Comments

The GG Modifier creates a second attachment point for holding a Grigri upright, eliminating the need to permanently modify the Grigri for Lead Rope Solo climbing.

Bliss Climbing Tech states the following on their GG Modifier product page:

Safety Notice: Note that Petzl forbids HERE the use of the Grigri and NEOX for LRS [Lead Rope Solo] and it is dangerous to do so. The Grigri is unsafe for LRS and the NEOX more so. The GG Modifier does not make it safer.

DO NOT CLIMB SOLO! Nothing can make solo climbing safe.

Yann Camus of Bliss Climbing Tech sent me the following note describing the materials used:

The pink cord is made of Polypropylene (PP). The new black cord is Nylon, offering greater abrasion resistance and slightly higher strength.

All the gold GG Modifiers I sent you are made of PLA, while the grey and blue ones are PETG. We’ll be transitioning to 100% PETG soon since it’s more UV-resistant and durable, even though PLA has slightly higher tensile strength (but is more brittle). The PLA was 'good enough,' much like the pink cord, but now the materials are more optimized.
