4 Gang Relay holder

I wanted a away to arrange accessory relays in my engine bay without rewiring everything. They make very nice relay/fuse boxes that require you to rewire everything into a very neat and tidy box. those boxes are great, but they are bigger than I wanted. this allows you to simply unplug the relay, insert this between the relay and it's plug, and go. nothing more complicated.I printed mine in black hatchbox ABS with the predefined settings in prusaslicer. I did add infill to the vertical mount. i figure that using a self tapping screw there will be some crushing forces that a low infill might not survive. So I used 80% infill there to help strengthen the screw holes and vertical mount.

I modified the @ZeroGeek file to allow 4 relays in a 2x2 arrangement.
I also:

• thinned the base by 50% to allow more are of the relay tabs to be in contact with the adapter below.
• moved, enlarged and recessed screw head hole to allow mounting
