This is a pretty simple bottle opener that can be mounted on any bike that has a front derailleur mount. I made this for one of my friends who did a 1x conversion and wanted something functional to attach to the mount where the derailleur used to be.
The base of the opener is 3D printed and the opener itself is a generic Amazon bottle opener plate that was bent on a sheet metal brake (bender) and screwed into the base. I also incorporated a magnet in the opener so you don't lose any bottle caps and accidentally litter.
