So I use a shuffle on my mountain bike and many times find it un-clipping on my camel back or if its there hard to use the controls.
Decided to design and make a solution and here it is.
I designed it in Solidworks and then printed it out in my Davinchi Jr. Cant wait to upgrade the printer!!!! It has slots made to accommodate zip ties as the method to secure the clip to the bike.
Works great!
