I took the original design (albeit the slim design version) and have remixed my own version in TinkerCAD. To be clear, I actually started from scratch and created a brand new model, but used the slim version of this model as my basis. For this reason I wanted to credit the original creator as they helped me figure out the idea of how I wanted it to look. This was designed specifically to fit on the side of a Sterilite hip hold laundry basket just below the handle on the side. These are in a laundry tower in the laundry room, and these signs were made as an easy indicator of the status of what was in the bin at any given time.
Please note, I wanted them to be of a decent size so they are easily identifiable and recognizable. For this reason, they don't fit from the outside just slipping in under the handle. You actually have to reach inside the basket to lift it up and flip or remove, etc. Technically you can fit it through the handle space at an angle, but you will slightly flex the part which won't be good in the long run. I'm sure PETG is an option also to account for it, but the tolerance is quite tight and not as easy.
For printing, I added a layer adjustment to make the infill 100% above 5mm. This ensures that slim pieces are as strong/sturdy as can be. Printed at .2 mm heigh and standard PLA temps and adjustments.
