E3d Chimera or Cyclops mount to an Ultimaker 2 Clone that could be added up to two blowers fans (5015) and an 8mm inductive sensor. A 30 mm fan could be assembled to the Hotend.
E3D original Chimera and Cyclops, All-metal and Chinese versions fit well on this models.
Super Glue could be needed to set the position of the fans strongly.
The threads are M3.
The Rods and hotend mount print them with 50% infill and 1.2mm shell thickness. The rest with 25% infill and 0.8mm shell thickness is enough.
The inductive sensor mount is the unique piece that needs supports.
