I cut a notch in the HDMI extender so that it’s held in by a friction lock when the case is closed. It’s actually a really solid connection and easily withstood my 5 year old son tripping over the controller wires and bringing the unit crashing down. The Pi popped out of the HDMI extender and I just needed to plug it back in. The extender is worth the $2 it would cost on Amazon.
