Pomona 6883 Binding Post Mounting Plate

I designed this plate to upgrade the cheap spring loaded binding post in my Dayton 652-Air speakers. I used Pomona 6883 dual binding posts, but it may fit similar binding posts. (The 6883 has approximately a 3/4" center to center distance between posts.) This was my first 3D design and I'm definitely not an engineer, but hopefully it will be useful to someone. I can post the FreeCad file if anyone would like to customize it for their own purposes.Printing:I used some off brand Black Carbon Fiber PLA I had from amazon.0.2 Layer Height20% InfillNo supports necessary.
