Bottle Clamp 60 mm Airgun

These things are quite expensive in metal on the internet and I thought I could do a great job creating it on a 3D printer in PETG because of the flexibility combined with  strength. Had to adjust sizing to fit the exact ISO picatinny measurements. Challenge is that the ring has a maximum thickness of 2 mm else it won't fit between bottle and barrel. Made somebody very happy with this.
