Bose SoundSport wireless charging case clip

I bought the Bose Charging Case off Amazon to only find that it doesn't have a way to clip onto a backpack like the soft case that came with the headphones. So I designed this one that screws to the top (opposite of the charging side) with 3mm screws. That way you can now use the carabiner that came with the soft case on this charging case. I hope you enjoy, please leave comments if you want changes or some other design.
