Sunhokey i4 fan mount. 4 Models

I made 3 models for the Prusa i4 hotend fan,and one for radial fan 50x50mm, with adjustable height mounting. I use the "Medium model" this Work for me.
I also use the BlackSilent Fan XM-2 - 40mm from Caseking.de this models give a medium Wind. If you want strong
wind, you have to find another fan
