Part is hollow, slit is just on one sideI can't shake the feeling that those white pieces are some sort of fluid reservoir from a car, RC engine, etc. I know they have those "slits" but is it confirmed that the slits go all the way through to the main body of the reservoir? Could they just be recesses to allow the tank to sort of "snap" or "slide" into place?
BUT the original part had those „arms“ on both sides IMHO...you can see that they cut one side off
