This is a computer-style fan designed as a concept to show the kind of geometries you can produce with a typical 3D printer. To make this fan you need to download two STL files and acquire two common ball bearings (4x18x12mm).The 3D-printed parts consist contain some challenging geometries such as steep ang extreme angles, as well as perfectly flat surfaces which are not printable without the use of support structures.If you are note familiar with 3D-printing using support structures, settings optimisation, etc, then this is the perfect model for you to step up to the next level!
Quick light design for all of you, who wants to use standard 120mm PC fan to cool your prints (area cooling). No need of supports, no germane overhangs. Fits on 120×120×25mm fans. Just print two pieces with common settings. There are holes for long fan screws, but it will hold even without one (friction).This mount is especially useful if you use heated bed with PLA, what is a bit deadly combination (code name: overhangs). Fan will be higher than 60mm from the pad (made with Printrbot Simple Metal users in mind).
