An improved design over my previous cooling fan arrangement. This version attaches the fan to the X carriage.



Print one of each part.

Put a M3x18 or longer bolt through the two parts to create a joint.

Use M3 bolts to attach a 40mm x 40mm x 10mm fan.

Attach to the top of the X carriage using the four existing accessory bolts.

Angle the fan so it is pointing down towards the hotend and tighten the bolt at the joint.

Really helpful thanks for putting this together and publishing. Should take care of some of that excess heat.

Nice one. I uploaded the 2 files into TinkerCad and printed them together. Small bit of filing and we were there. First upgrade! Thanks.

I made two of these, one fitted with a fan as show in the pictures, and one i fitted with two white leds with reflectors to provide some light on the bed.

It connects to the spare screw terminals on the Melzi board.

I don't get what spare screw terminal you are talking about. All of the screw terminals on the Melzi board are used as far as I know.

how do you control the fan? I have a rrp mendel but not sure where on the board to find power for the fan. Any ideas?
