Yet another soap dish. Features an inclined bottom to make any excess water flow out.
Material: Doesn't really matter. Go with what you like.
Support: None. The updated shell does not require any support. The original shell (not recommended anymore) does need some support for the lower parts of the fillet.
Infill: No special requirements. Use the minimum amount that is needed to support the top layers.
Perimeters: That's up to your preferences. I personally recommend 3 perimeters to get some durability.
Orientation: I strongly recommend to print the tray upside down. This will give you a much nicer visible surface finish. The shell must be printed bottom down, as it is, obviously.
The overhangs of the rounded edges of the original design are a pain to print. I've added an updated shell where the overhangs are reduced to a maximum of 45°. In my experience that should always print cleanly without support.
The tray snaps now into the shell.
