C.O. Bigelow Transfer Coupling

prusaprinters

I prefer to refill travel size toiletries from the normal-sized container whenever I can. It reduces waste and saves money.This coupling is designed to connect C.O. Bigelow aluminum shave cream tubes. Squeeze any air out until the shave cream is starting to come out, then screw the tubes in til snug. It works with both new (clean) and used (a bit crusty) threads. Squeeze from the bottom-up on the new  new and watch the refill expand. When finished, simply remove, cap the tubes, and rinse the coupler for next time.This can work for other types of toiletries, as the aluminum squeeze tubes are rather common and appear to use similarly sized threaded caps.Print at 0.15mm resolution - slicer defaults are fine. Works great with PLA.
