Lightning Adapter Holder - Non-Flex Filament

Just a quick (and admittedly rough) remix of Maker1893's Lightning-Aux Holder. I cut a "finger-sized" notch out of the back so to make it easier to remove the adapter. This should allow people to use non-flexible filament (PLA or ABS). I don't have a printer on hand, so I can't test this. Please let me know in the comments how it goes! Enjoy!
