Liquid Hand Soap / Dish Liquid Last Drops Collector

No one has the time and patience to hold the hand soap bottle and wait for the last bit of soap to flow down, so usually the last few ounces are thrown away along with the bottle. The same is true for dish liquid. Waste no more, print out this design to effortlessly tranfer them to a new bottle or get them into the dispenser.

It’s simple to use: Remove bottle caps, put the collector onto the fuller refill bottle (see first photo) or dispenser (2nd photo), then place the near-empty bottle upside down on top of the collector. IMPORTANT: Make sure the side labeled “TOP” is up and the “BOTTOM” side is down, as shown in the last photo. Otherwise, the hand soap will not completely flow down into the dispenser or bottle below and may spill out.

In addition to hand soap, it can also be used to do the same for some other household liquids. I have used it on dish liquid (see 3rd photo) and big bottles of hand sanitizer without needing to scale the model up or down.
