Plastic standoffs that snap into the screw holes of the type used in some computer cases. That is a nub on the bottom of the ones I've seen for cases that could be cut off and some sort of super tape, I think 3M has something like this, could be used to attach these feet to the inside of case, all without putting any holes in the case. I'd love to find a source for these with or preferably without the nub thing on the bottom, cheap out of CN would be fine for me. But perhaps you could find some of these things for your project from an old computer case or system you could gut. Oh, and if you don't have the super tape, I'm thinking a dab of hot glue.Does anyone know where I can get 16mm M2.5 PCB standoffsspacers in the UK?
Can anyone suggest anywhere else? Is there an alternative to standoffsspacers that I'm missing?
