Ender 3 v3 se upgrade to 40mm and 5015 fans +KE hotend option

This is my version of Ender 3 V3 SE cooling upgrade to dual 5015 fans, 40mm silent hotend cooler and LED (optional).

I decided to use 12V 4010 cooler due to was planning to connect LED to the same DC-DC step-down converter.

To assemble you will need:

• 5x M3x8mm screws
• 1x M4x20mm screw
• 1x M3x40mm screw
• 4x M3 heat inserts (for 4010 fan)
• 4x M3x14mm screws (for 4010 fan) 
• 2x 5015 24V blowers (designed it for GDSTIME dual ball bearing 6000rpm fans from AliExpress)
• 1x 4010 24V or 12V radial fan (I have 12v Noctua)
• DC-DC (in case you going to use 12V 4010 fan).
• soldering set to change fan connectors and combine 2 x 5015 into 1 connector.
• heashrink tube for wires isolation
