MakerX G300 2 Fit and Finish and Connectors 

I talked to them directly and they responded back. It seems that is coming.

Ever pay attention to how long rubber bands last? Ever try this to see if it's true or not? I'm going to posit that you need some seriously powerful rubber bands to put enough pressure on the connector to pull it down tight. I'll hazard a guess that no rubber band that will fit around the screws will work.

It will still need a heat sink, but it does make for a good heat spreader.
