This is a replacement for the noisy, low quality electronics fan that comes with the Ultimaker Original.

The supplied fan has some well documented problems with its bearings - they get noisy and need regreasing from time to time. Mine started making a lot of noise and didn't seem to be completely repairable, so I designed this.

This design uses two 40mm fans (I used these: http://www.amazon.co.uk/gp/product/B00BF3S83C) and only replaces the original fan. That means there's no need to print a whole new cover plate.

The two parts of this design need to be glued together and then attached to the wooden cover plate with a small self-tapping screw (or you can use a through-hole screw and nut if you want).

Materials and methods

Super glue
A small self-tapping screw
