Better Hot Wheels Starter Connector for B5696

This is a replacement part for this Hot Wheels Double Starter (B5696 Picture).
Normally you should be able to connect the standard tracks, but they simply slip out.
So I designed this quick replacement part.

This is the updated V2.
I printed my first version and am satisfied for my use. I recognised some flaws and fixed the design. Though I didn't print and test my V2.

You probably should print with supports at the side-overhangs.
