CR8 TMC2100 Fan

This is for the CR8(made by Creality Inc). After you change to TMC2100 Stepper motor）,You may need to increase the coling system .So I made it for CR8.It use the old Fan in the floor of CR8 Case.and No more screw will be need.
it still give about 30% to the mainboard and 70% to TMC2100 ,But it pn;y give the wind to the X Y step motor,If you change 3 or 4 step motor,this design can't work well.
