I had to make the stem as close as possible to the hole size so your going to have to do some cleaning on it to make it fit properly. Make the stem to loose and the soap leaks out as your squeeze it in. I used PLA with 100% fill. Just to give it some strength when your tightening. But ABS might work better as it flexes more
