I really liked the original design but when I printed it I found that the internal fillet made it so that the cover just wouldn't seat properly and instead kept popping off. I squared up the internal corners and also added an inward leaning angle (negative draft) to the vertical walls to provide better holding onto the charger.
I print with Sainsmart TPU and have printed over a dozen now with great results.
