Prusa i3 Central Fan Mount

Central 40 mm fan mount that may be attached to standard holes on Wade's extruder.
Provides cooling both the extruded material and hot end's ribs.

Tweaked a model after it has been printed on a Prusa i3 printer by Jelwek.

Wall thickness has been decreased to 1 mm as 1,5 mm was not needed.

Inner diameter is 13 mm - check Your hot ends ribs diameter to ensure it will fit correctly.

Tried to make as easy to print as possible even with overhangs - just remember to use cooling printing
