Ender 3/3 Pro PSU 92mm Fan Adapter
Description
this is kind of a remix (i was not able to use original design parts so just designed it from zero using same general shape). NOTE: For the mean while PSU i suggest tou to use the specific model (Ender 3 PRO) For the basic PSU (ender 3) pick the Generic model (it hase 4 holes on the mount side) NOTE 2: most probably u will need to invert the polarity on the jst connector, before changing or unwire the original fan make some photos. Mine is an Ender 3 PRO i do not know if the ender 3 PSU is using 12v fans, if not u will need a buck converter. HARDWARE: screw driver (star, with the diameter <= to the diameter of the fan mounting holes) 92 mm fan (with open corners, take a look on the one i linked) NOCTUA redux 92 mm is perfect. no matter at all if u will use the 4 pin or the 3 pin version, psu controll it by the voltage. 4-6 standard fan screws Glowes (to prevent shorts could happen that some caps are not discharged) optional: 92 fan grid (to cover the outside of the fan) 2-4 more fan screws some electrical tape(better avoid) 2x heat shrink 15mm each if u will reusing the same connector of your original fan and solder it. requirements: basic understanding of polarity and voltage. wiring/soldering/pinning ability to avoid hurting yourself: 0 use gloves, maybe 2 pairs if u are using clinical ones 1 switch off the printer 2 UNPLUG the power cable of your printer. 3 with the removed power cable turn on the switch on the power supply (it should in theory discharge all capacitors) 4 dismount the PSU and remove the cover 5 DO NOT TOUCH CAPACITOR PINS 6 if u do not have experience with electronics just avoid disassembling your psu. 7 wire cables with respect to the polarity of your psu, (on the ender 3 pro the fan should be 12v double check on the psu fan lable, if u put a 12v fan on 24v power out your fan will last 2 days) 8 figure out how to pass cables from inside to actual fan (i did it simple, just send it trought the under side and zipped it to the PSU frame) 9 if u are noob at this but still wanna try it out, be carrefull and watch some youtube videos, its quite simple work but still can be dangerous, mostly because AC cables are in fact accessible even without removing the plastic cover. 10. if u dont know what u are doing, please just avoid modding your machine, appart the dangerous of take an electrical shock, modding 3d printers could provide u a ton of problems and failed prints or in extreme burned house. NOTE: the fan must be oriented to SUCK OUT the air. It will not work properly in different orientation and your psu will overheat. Noctua fan i used (Note the corners of this one, all mounting holes are accessible from all sides): https://www.amazon.it/Rascom-GmbH-NF-B9-1600-NF-B9/dp/B0014I9K30/ref=sr_1_2?keywords=noctua+redux+92&qid=1644145182&sprefix=noctua+redux+%2Caps%2C113&sr=8-2 IMPORTANT: this converters are not required, but since i dont know the voltage off all PSUs that can be used by creality im giving links for ppl that maybe doesent know what is a buck converter.(dont worry links are not affiliated and i will earn nothing from it XD) Buck converter (just for example, find a better one) LM2596 https://www.amazon.it/Hiletgo-LM2596-DC-DC-converter-1-23-V-30-confezione/dp/B008BHAOQO/ref=sr_1_18?keywords=buck+converter+step+down&qid=1644146153&sprefix=buck+conver%2Caps%2C101&sr=8-18 there are silent models, but since i dont care i just pick a basic one. Very Nice Enclosure for the lm2596/lm2596s: https://www.thingiverse.com/thing:3164882
