Lenovo Thinkpad T14 Fan Deflector

thingiverse

[ Problem ] I work with this pc {Lenovo ThinkPad T14} and since I use the mouse close to the pc next to the exhaust fan on the right side of the pc, I find the heat annoying and unbearable in the long run. I saw other solutions on Thingiverse, however none of those had low profile, and allowed the screen to be closed and keep the deflector at all times attached to the pc. [ Design Solution ] I decided to sacrifice the first and last grate holes from the exhaust and use them to attach clips with hooks that keep the deflector attached with low-profile and without the need to have clips that grab the whole side of the pc. [ Testing ] I've tested it for a 5-days working week, in which the computer was used with heavy load graphical apps for 8 hours a day. The pc sustained extended periods with the fan at max rpm in which the deflector didn't change shape due to heat stress and was kept solidly in its position by the clips. During the week I had to travel with the pc in a 14"bag and the deflector stayed in position during the whole time. It has a similar profile height of a usb from a wireless mouse, so it should fit in many travel bags. [ Printer and Set Up ] I've printed it using a Creality Ender 3 V2 with only the main structure left without modifications ;) Bowden extruder mounted on the top horizontal beam. [ Printer SETTINGS ] Considering the deflector has to sustain the heat stress from the fan exhaust, PLA it is out of the question. PETG it is a good compromise between ease of printing and strength and malleability characteristics. It also suits this design because of the lower breaking point of the PETG compared to the composite used in the Lenovo pc, meaning that, in case the clips get stuck, they will break before the grate of the pc will. - I've used PETG (first tested in red then printed last design in translucent) from CCDIY (very good quality/price Australian Brand). - 0.4 Nozzle - 0.16 Resolution - 0.5 Line Width - 274C HotEnd - 80C - 100C Bed - 50mm/s - 4 Wall line count - 4 Top/Bottom layers - 15% Infill - [ lines ] - 40% Fan Speed - Support (Main Body Only) 57degree overhang - Support touching build plate - Slicer: Ultimaker CURA 4.11
