<pre>Thx to Neon22 for his great customizable thing! The original thing and customizer can be found here: https://www.thingiverse.com/thing:1015874</pre> ****This a 120 mm fan to 125 mm duct adapter.**** The fan is connected to an activated carbon air filter (industrial version, check out Ebay and growshops). The guy who lived here before us was a smoker so we use this filter to clean the air from cigarette smell. I use this kind of filters for more than 10 years now and they work perfectly in our bedroom and living room, way better than the very noisy Honeywell we tried before. The old 230 V fan was connected to 80 V and it was almost noiseless but 25 W per hour was way too much for 24/7/365 (219 kW per year, ~65 €). The new fan is sufficient and quiet (Papst 4412 FGM 12 V@6 V, <1 W). It is running for several months now. ***Edit: It is a hot summer and I am also using this thing at my desk with a 12V fan@5V connected to USB. It works perfectly! Don't forget to add a (printed) protective grill. I use these two parts to connect my 12V fan to a power bank (5V):*** https://www.banggood.com/USB-Port-to-5_5mm-2_1mm-5V-DC-Barrel-Jack-Power-Cable-Connector-p-997025.html?p=X314171248723201502R https://www.banggood.com/5_52_1mm-DC-Power-Male-Female-Plug-Jack-Adapter-Connector-for-CCTV-LED-5050-3528-5630-Strip-Light-p-1111850.html?p=X314171248723201502R ****35° extension for this thing: https://www.thingiverse.com/thing:2353607 **** **** More 125 mm ducts: https://www.thingiverse.com/thing:2354806 **** ***Dimensions:*** Height: 55 mm OD: 125 mm ID: 122 mm Wall thickness: 1.5 mm ***Hint:*** If you plan to use it with an activated carbon air filter check the dimensions of your filter before printing. I have a Can-Lite 425. It lasts for around 2 years, then it starts to smell a little bit and needs to be replaced. Maybe it is possible to replace the activated carbon only (available on ebay). I did not try it. **** Customized version of http://www.thingiverse.com/thing:1015874 Created with Customizer! http://www.thingiverse.com/apps/customizer/run?thing_id=1015874
