Ballsack holder for bike
thingiverse
I wasn't happy about not having my balls perfectly centered behind my bike saddle, so I came up with a clever solution. I also wanted to be able to easily remove them when parking my bike. This is where the adapter comes in - it lets me unclip the little holder from my saddle without any hassle. You may need to make some adjustments to get it to fit your saddle just right, but you can access all the files and modify them using OpenSCAD. The latest versions of the files are available on my GitHub repository: https://github.com/clementleger/3d_parts (ball_holder folder).
