DESCRIPTION OF THE 3D MODEL This part was made to cool the bed faster when you are  waiting to remove your parts. It is compatible with the Ender 3 V2. You can check whether it is also compatible with your printer thanks to the measurements on the images. I am available for more informations. It is necessary to provide a space below the bed of 1cm at least. You can see the efficiency of the mounting thanks to the graph. The measurements were made with 2 fans 40x40x10 12v. This allows you to cool about 2 times faster with this configuration. To improve performance, you can use 24v fans. There are 4 M3 screw and nut locations on the sides to secure the fans to the printed part. The whole slips to pinch the bedbelow the main bed. Very easy to place and remove. The printing takes a little more than 3h with the indicated parameters. It is strongly recommended to print vertically. 3D PRINTING SETTINGS PLA layers: 0.2mm shell thickness: 0.8mm top/bottom thickness: 1mm filling: 50% Print speed: 80mm/s positioning speed: 80mm/s first layer speed: 20mm/s filling speed: 0 top/bottom: 50mm/s Shell printing speed: 35mm/s nozzle temperature: 210°C bed temperature: 60°C shelf hook: raft support: in contact with the bed minimum support angle: 45° horizontal distance: 0.7mm vertical distance: 0.3mm
