Soap transfer coupler for laundry detergent, fabric softener bottles, or anything else with the same type of thread pitch and size. holds it at a 30 degree angle so it drips back into the new bottle.
Put the captive cap side into the new bottle, and the solid cap side on the one you're transferring from or trying to empty.

Notes:
I tried printing it on either cap side, both worked. both need support though. I think I'd recommend trying to print on the captive cap side face first. I printed mine basically 100% solid since its so thin already.
