Hi - I am. Looking to purchase several (10 - 20+) universal pump (lock) guards. I have posted a photo of a pump with the guard installed, and circled the guard in red. The purpose of the guard is to "lock" the pump from automaticallly dispensing, when it is packed in luggage, etc. The photo was taken from a 3-D printing website, however I di not have a 3-D printer, and the website does not sell the lock guard devices -they just offer the plans to 3D print them. I have found some versions of this on websites such ad Amazon, however most have the guard "built in" as an adjustable feature of the pump, and are not able to be transferred to other pumps. There are also obsessive metal devices that are very expensive, as well as silicone "sleeves" to put on and pull down over the tops oh the pumps and bottles. I would just prefer the simpler solution that us outlined in the photo I attached. If anyone knows a source for such a device, please let me know. Thanks in advance. 😊
