open back bumper case for iphone 15

All the cases / bumpers that I could find either restricted the cooling or were ugly. So I made my own with an open back allowing the back of my phone to dissipate heat as intended. Another feature is that the phone's MagSafe functionality is not restricted, i.e. you don`t need a MagSafe compatible case. Print in TPU, no supports needed. You may have to slightly adjust the length to get a good snug fit on your phone. This is best done in the slicer by applying a multiplicator on the x/y-axis (e.g. 0.99)
