Anet A8 bigger Hotbed Mount for Y-Axis Cable Chain

I updated my hotbed on my Anet A8 to a 300 x 200 one ( here more on that https://www.thingiverse.com/thing:2477910 ) and therefore needed a longer chain.

Now like with all A8, my old hotbed connector turned brown so I solded on a new one.
I wanted to use an EC3 (60A) but ordered EC5 (120A) by accident. Anyhow I needed more space for the connectors and redisigned the chain mount on the carriage side, so bigger connectors would fit in.

I also designed a lit, which works but isn't really needed.
