Quick tool change DOUBLED!

Tool holder from original design, split in half.
Bottom body holds hot end, Top body holds fans.
Now you can change only the hot ends (I have one for 0.4 and second for 0.8 noozle).

I have made some prints in PETG, V3 works well for me.
Now, there is a V-slot between bodies to prevent it from sticking out when pressed with handle.
I am considering to put the V-slot at the bottom of original body too --> V4
