I travel quite a bit. Through the years I've collected a number of those miniature hotel soaps with the idea I could use them while camping. The commercial soap dishes are huge and a waste of space for the size of the soap. None of the soap dishes on Thingiverse met my requirement, a simple way to drain the water out of the dish. So I created the "Ultimate Travel Soap Dish".
I found the holes clog after about 3-4 days of continuous use. Since I'm creating the "Ultimate Travel Soap Dish", this was unacceptable. I've added a new design ... a notch. If it is good enough for my phone ... it is good enough for my soap dish :-). Partial top placement exposes the notch and allows the water to drain without issue of clogging.
I've designed three sizes:
Small: Perfect for a complementary hotel soap. I've designed it to fit most of the soaps found in Marriott, Hyatt and Hilton properties.
Mid-Sized: Can hold two small soaps stacked. If you scale up slightly you will be able to hold some full size soaps.
Full: Holds a full bar of soap.
All three sizes include drain holes or a notch. To drain, place the cover on part way making sure to expose the notch or not block the holes . Once the water is drained, close fully for a tight fit.
I recommend using .3mm layer heights. The soap dish uses friction to hold the top in place. The uploaded lids are exactly .6mm larger than the bottom. Scale the cover in the XY direction as necessary to produce a tight fit.
Bonus points the the first person who can identify which hotel supplies the Zest soap bars. Leave your guess in the comments.
Double bonus points ... which hotel supplied the round soaps?
