Simple mount 3x3cm

I designed this simple mount to attach a battery to my bike helmet cam, But it is so generic that you can use it to mount ANYTHING with a double sided tape.
The cool thing is that it doesn't takes much time to print, Does not need support and allows you to remove the mounted device quickly and easily.
I made sure it slides into the mount base easily, But not too easily.
I've also included seperate .stl in case you want to enlarge a part to make it tighter or looser.
