There's a little black doodad on Gojo automatic soap dispensers that hangs on two motor-driven pegs and pushes on the collar of the soap bottle to dispense the soap. One of my office's bathroom soap dispensers was missing this piece, so that the pegs tried fruitlessly to engage with the neck of the soap bottle and usually failed. Nobody else was interested in fixing it, so using an OEM doodad as a model, I designed this (very stripped down) piece that does the same thing. It's missing some of the swoopier elements of the original, and it's also missing a hook on the back that slots into a section on the back of the soap dispenser, but it appears to be functionally close enough to the actual thing to work reasonably well as a replacement. That having been said, I take no responsibility if you use this replacement part and it somehow mangles your soap dispenser by failing to perform some expected function. It's better than nothing but probbly not as good as the correct part.

In the attached photo you can see the new piece in situ (it's the yellow collar). The collar should be open in front, with the larger section downwards, and the two holes grasping the pegs on the side of the channel through the soap dispenser. When a bottle of soap is inserted, it should hang with the narrowest section of the pump through the narrowest section of the actuator, as seen.
