Tronxy X3 Supercooler - hot end fan shrouds

thingiverse

UPDATE: Check out this Mitten Cooler newer design I just released. It should work well and only requires a 5015 fan. My stock-built Tronxy X3 printer's hot end couldn't go above 205ºC. The stock design cools the heater block too much, making it impossible to print with higher temp filaments like >220ºC. So here is my solution. It reuses the screws from the hot end radiator but only works if you remove the washers. This design is for left and right 30x30x10mm fans (12v) but you could get by with just one. If you add the left one, then you need to use my custom x-stop. Custom x-Endstop: http://www.thingiverse.com/thing:1906501 Wire the 30mm fans in parallel and added my own y-connector. If this is helpful, a tip would be nice - at least a like and show your makes. Assembly video: https://www.youtube.com/watch?v=aMM67JGe3qQ Please note that this design isn't compatible with the auto-leveling sensor. If I get enough requests, I may figure something out. Printer Settings Print on a Tronxy X3 Rafts: No Supports: No Resolution: 0.15-0.25mm Infill: 20% Notes: Print one in PLA and then use it to reach higher temps; reprint in ABS, ASA, or PETG. The heating element wires get warm and will warp a PLA version but my ABS shows no issues after many hours of printing. Don't over-tighten the screws mounting the fans or you risk stripping the screw holes on the shrouds. Post-Printing For PETG, I've been running the part cooling fans at 25% and they seem to work well. Design Process As usual, my gateway design tool is Onshape. I started designing this project on my iPad but then switched to my desktop for finer control with my mouse. It was faster - although not as comfy as designing on the couch with my dog by my side.
