Snapable Drag Knife Mount for Prusa MK3S

This is a remix based on the Drag Knife Mount for Prusa MK3S by Jonas Pedrotti. The main change is that it now snugly snaps to the fan based on the geometry of the Fan Guard by Der Peiner. Other changes include prinatability improvements and increased clearance for larger part cooling fan shrouds. This model is suitable for use with ‘Roland’ style drag knife holders.
