Hub fix for Kobra 3 Max.

This model changes the hub install on the Kobra 3 MAX printer. Removing the screws from the hub is done from the back which causes problems when trying to do that with the printer paused to the right. This model uses the existing screws to attach the model. Then 2 new screws attach the hub from the front. These screws go into heat inserts and are not subject to being stripped out. This model can attach any of my other 1,4,5,8 or 9 port hubs although a stock hub will work too. Two M3 x 14 screws are used to connect the hub securely. M3x14 screw can be found here.
