Created a charging stand for my sons' Gizmo smart watches, only to find the first run was waaay big -- included it anyway; the considerably smaller, prints-without-supports, artsier version is included as v2.
Does not accommodate the charger at full depth because it's obnoxiously thick. As a result, the tolerance on the groove that holds the charger itself is very tight. You can scale this up by tiny amounts or route out small chads if you're having trouble, though if you go too loose it won't snap in place anymore.
Unless you have amazing bridging capabilities, the v1 variant should be printed with supports. I found that even with supports, considerable post-prod work is required to ensure good fit (which is why I redesigned to be printable as a unibody piece without supports).
Infill is up to you, but I wanted it a little heavier so that it gets knocked around somewhat less.
Included source Sketchup files in case you're curious.
