3.5" floppy drive bay USB port mount

I had a couple 9 pin USB port cables left over from a PC build I did back in 2012. I wanted to connect one to the headers on the motherboard of an old retro computer I recently acquired, and I wanted to expose it through the case's extra 3.5" drive bay.  I couldn't find any suitable models, so I made my own. The OpenSCAD file is included in case you want to make modifications, but fair warning: I put this together pretty quickly and so there are a lot of places where I should have used variables but instead just hardcoded values. (At least it's a simple model!)

The particular bay I'm using has a screw hole for mounting a HDD as well, so I've added a hole for that in my model and am using that hole in the photo I've included. I printed the whole model in order to test the holes I included for a standard floppy bay, but if you're likewise planning on only using the HDD holes, you could just stop the print once those have been printed (or truncate the model in your slicer) and save some filament.

My USB ports take M4 screws, so that's what I've used for the holes on the sides of this bracket as well. To mount two ports as I have, you'll need six of them in total.
