Bondtech Arrow - modified for dual fan 4010 - CR-10 Smart

I have modified the Arrow design from Bondtech to allow the assembly of 2 x 4010 fans on the CR-10 Smart 3D printer.

The original design is made for the stock hotend( i have installed it on microswiss hotend without issues), and Bondtech LGX Lite extruder, so you will need this if planning to do the upgrade.

All parts printed 0.2 layer, 35% infill, 3 perimeters with supports.

Printed in PETG, sliced with superslicer on klipper format, but i guess any slicer will do.

Mechanical parts needed (taking in account also the assembly of the extruder):

• M3 x 20 screw - 2 pcs
• M3 x 10 screw - 4 pcs
• M3 square nut - 7 pcs
• M3 x 6 screw - 4 pcs
• M3x30 screw - 1 pc
• 4010 fan - 1 pc 

Soldering will be needed for the wires of the two 4010 fans or other connection method.

I am not taking credit for this design, I only modified it. The concept and design is Bondtech entirely.
