There are two sizes of connector in this set. The smaller one works well with many types of hand soap, dish soap, and lotion. The larger connector is meant for bottles that don’t fit the smaller one, like Old Spice body wash and shampoo, Head and Shoulders, and so on. In any case, if the small connector doesn’t work, the larger one usually does.

Printing recommendations: 3 perimeters, 15% infill, layer height of 0.15–0.20 mm, with supports placed only on the build plate (for the inner ring).
