Ender 3 S1 Dual 40mm Fan Hot End Duct

cults3d

v1 Installation Guide: You will require the following: 6x M3 10mm Screws. (You can get away with 0 if you want to use glue) 6x M3 Threaded inserts. (See above) 2x M2.5 Threaded inserts. (You do need these) You can probably get away with using some adhesive for the fans and bed levelling probe but I don't recommend it Steps: Insert the threaded inserts. I used a soldering iron and pre screwed the M3 bolts so that melted plastic doesn't get stuck inside the inserts making it very hard to fully screw the bolts in. Screw the Fan Shroud onto the hot-end assembly. You will be using 4x M3 bolts that come with the printer. 2x from the CR-Touch, 1x from the existing fan shroud and 1x from the 4 bolts that are used to attach the hot-end to the X-Axis bracket. (3 screws are more than enough to keep it secure). Screw the CR-Touch into the shroud and route the cable using the groove in-front the hot-end cooling fan. (The existing cable to too short to nicely route it) Screw the fans into the shroud Screw the breakout board into the shroud Connect cables, this will be on you how you decide to wire it up. If you go for a buck convert, resistors, run the fans in series. There are many methods to connect 2x 12v fans to the Ender 3 S1. You will need to level the bed after. See uploaded GIF FAQ:Can I print this in PLA? Maybe, I wouldn't recommend it but at the same time mine is currently printed in PLA. There hasn't been any deformations after 30hours of printing but I also haven't done any 10hour+ prints. Can you make one that doesn't require threaded inserts? Yes, no ETA. Does this weigh more than the stock cooling assembly? Yes, by 10-20grams. Do I have to print with everything supported? Actually no, the inside of the part cooling shroud doesn't need supports when printed on an Ender 3v2 with the Briss cooling shroud, but I will leave that on you to create a custom support blocker. How's the hot-end cooling? Is it better than stock? I don't have any numbers for you, don't have the equipment to get them either. All I can say is after a 9hour print the heat break heatsink was warm to the touch. What about the Part cooling? I haven't had any issues with my prints. What's next, v2 when? Probably not anytime soon, this is already version 13 before I felt it was fit to release.
