I created this offset mount for my fabric bottles in order to mount two of them to my Canyon Grail. The usual mounting points don't work since the bottles would interfer with each other.
The offset is 20mm. You can also easily customize the step file or take as reference for different offset.
I used aluminium M5x20 screws for weight saving - now the offset mount is lighter than the original knobs with its steel screws.
