Ultimaker Replacement Electronics Fan

youmagine

This replacement is designed to eliminate the noisy, low-quality electronics fan that comes standard with the Ultimaker Original. The supplied fan has well-documented issues with its bearings - they become noisy and require regular regreasing. Mine started making excessive noise and didn't seem completely repairable, so I created this alternative. This design utilizes two 40mm fans (I used these: http://www.amazon.co.uk/gp/product/B00BF3S83C) and replaces only the original fan. As a result, there's no need to print an entirely new cover plate. The two parts of this design must be joined together with adhesive and then attached to the wooden cover plate using a small self-tapping screw (or you can use a through-hole screw and nut if preferred).
