Plastic to sheet metal snap

[abhinj]

hello ,
I would like to design an sheet bracket for plastic component . The plastic component has snap and a snap cut put at its rear and we should make use of those 2 available features to fix sheet metal bracket . Screwing is not allowed to assemble plastic and sheet
i need info on the available techniques / design guidelines( sheet deflection , depth, angle , force needed to snap etc...) to create a mating snap fit to fit existing snaps on plastic part.

Please find the attached image for reference

However, I will speculate and comment a bit.

Getting one plastic snap feature to interface with one punched hole in sheet metal is possible, not necessarily easy.

Getting two plastic features to line up with two sheet metal features is pretty near impossible because of differing standard tolerances, unless you can provide a _lot_ of flexibility between the plastic features.
