Living in a college dorm, I found myself unable to cary a bar of soap back and forth to the bathroom without making a huge mess. And yes, I know I could buy a soap container for relatively cheap, but I'm an engineering major with a 3D Printer, so I wasn't about to do that!
This handy travel soap container has outer dimensions of 4 1/8" L x 2 5/8" W x 1 9/16" H. It should hold most standard size bars of soap (I tested it with Irish Spring) and has small tabs that lock the lid in place. To open it up, gently squeeze the sides and the lid comes right off. There are grooves in the bottom of the container that allow the soap to sit above the bottom and should help it drain a little bit when you put it in there.
My print is multicolored because I had a few filament scraps that I was wanting to get rid of. But, I used 3 different types of PLA (Prusa Silver, Prusa Galaxy Black, and AmazonBasics Blue) with a .3 mm layer height and 15% infill. Printed out without a problem.
