X Bracket (SCS8UU) Updated

This is and updated X Bracket that was uploaded previously. I found that the earlier version had a problem with the belt working loose after a while.

Also included are the three other parts of my hotend assembly. I have been trying to make one that is easy for maintenance, and also hotends for both 3mm and 1.75mm filament that are easy to change.

So far i have it reduced to 8 bolts, a 12 way pluggable terminal block and a 4 way for each extruder motor. Other suggestions would be welcome.
