Mazda MX-5 radio fixing bracket (for Sony XAV-AX3005DB)

Needed to somehow fix my aftermarket radio (Sony XAV-AX3005DB) in my car (Mazda MX5, NC1). Came up with this solution, which is kind of similar to the stock radio mount (which is also only affixed on the frame).

So if someone has the same combination of car/stereo, it might be useful.
