Love those large push button liquid detergent bottle but hate the cups? Finding it hard or annoying to hold the jug while pressing the button to dispense the detergent?

Well I felt the same way and I wanted something easier. The first thought was to just attach a hose to the end of the push button nozzle. But that has a lot of dripping issues. So I came up with this design instead.

The idea is simple. Replace the cap with the push button nozzle with one that can have a hose barb attached instead. Then, put the push button cap onto the receiver that also has a barb fitting on it. Then with a couple of hose clamps (zip ties) and your ready to go.

This is still a WIP. I still dont have the threads perfect enough to prevent leaks without using large amounts of Teflon tape or some other gap filler. Use at your own risk.

Ive also designed and included some 1/4mip to 3/8th barb fittings. You are better off purchasing some Nylone ones from the store. But that sort of defeats the purpose of the 3D Printer.

Ill get some good pictures of it once ive finished the next revision. Feel free to make your own modifications.
