I'm No Hero - Hot End Fan Shroud

thingiverse

I installed parts from the Hero Me collection on my printer, but I wasn't thrilled with how it attached to the carriage. I found a different Hot End fan that fit much better, but the fan duct didn't match up with the stock fan. So, I mashed them together. I used the fan mount and duct from the Hero Me and merged them with the back mount plate for the carriage using Tinker CAD. The mount plate ring prevented me from mounting the BL Touch as it would hit the part cooling duct. I created an offset BL Touch mount to resolve this issue. Additionally, I remixed a bowden tube brace to function better. This design should work well for the stock hot end, although I've switched to Microswiss. The nice thing about the mount plate is that the hot end can be secured to the carriage before mounting it in place. It also utilizes 2 of the stock screws from the original fan shroud and 1 additional screw with a nut on the back side of the carriage plate. With these 3 screws, it's incredibly solid. I also built a fan adapter so that I can eventually swap out the stock part cooling fan for a 40x40x10 silent fan. You can use the stock part fan or add the adapter and install a 40x40x10 fan instead. Recently, I created an offset mount for the stock ABL as well. Everything prints exactly like it's supposed to in Thingiverse, except for the adapter. That should print with the fan opening facing downwards. UPDATE 3/3/2020 I reprinted the entire setup using "True Red" PLA + filament from Microcenter. I added a box to the bowden tube stabilizer to hold the buck converter for the Noctua fan. This reduces the voltage from 24v to 12v, making it a nice platform for the converter and all the wires meet at the fan. It seems to be working pretty well so far. I also reformed the 40mm to duct adapter to make it more compact. The red filament looks great with the red accents on the CR10s Pro. One person asked about the position of the BLTouch sensor, and I simply eyeballed its placement relative to the nozzle tip. Then, I used the Z+ and Z- with a feeler gauge to adjust the offset for the nozzle and press home to save the change. It works really well in all aspects.
