I needed a euro (50x25mm) module that accommodated a shuttered LC fibre coupler (see my other items). While I was not surprised this didn't exist already as my needs were a bit specific, I was a little disappointed there was no basic euro modules that worked well for me.
I've included two designs - the type A is quite common with two clips, and a type B which has a clap/slot to locate and a single clip. Type B will be stronger on the clamp end, but isn't compatible with all faceplates.
I've found these to work fine without any supports, however I do tend to paint on supports for the bottom hooked parts of the B type. The other clips tend to be fine without as the overhang is quite minimal but YMMV.
I've a couple of other models based on this:
