Vertical Mount Direct Extruder for Chinese J-Head

Adapted this design to:
*mount vertically
*hold J-Head (Chinese made - extended top portion)
*added mount for 25mm to cool J-Head
*added inset for raised ring on stepper motor
*changed idler bearing mount to accept bearing on hand
*increased clearances on all nut traps
Still need to change dimension of one side of idler bearing mount to better fit over edge of raised ring on stepper motor (currently sanded it down).
