SummaryI designed this sponge holder to allow for better air drying and help to minimize bacterial growth. I use 3mm filament for struts and rivet the ends neatly with a woodburning kit. To attach to a wall, I used thumbtacks or screws, but silicone would work well for tile. http://youtu.be/0JjWi9Too6oInstructionsDesigned to print with no support. Use a woodburner or soldering iron and some 3mm filament or plastic rod to make rivets on both ends. The Soap snap is attached the same way but using a small length of filament.
