GoPro TRI-Suction Mount Adapter

I designed this mount adapter for my Hero5 and Hero5 Session to mount more securely to my car. I saw another tri-mount on here, but it wasn't beefy enough for my liking, also I decided to try and keep the mounts as close to one another as possible, so as to minimize vibrations. It's printing as I type, and will update after I get a chance to take some pictures and try it out.

Comments are welcome! I'd love to hear feedback. Thanks!

It looks like most Ebay suction cups that are 5.4cm in diameter would work.
