Tronxy X3 Supercooler - hot end fan shrouds

UPDATE: Check out this Mitten Cooler newer design I just released. Should work well and need only a 5015 fan.

My stock built Tronxy X3 printer's hot end could not go above 205ºC. The stock design cools the heater block too much. I wanted to printer higher temp >220ºC filaments and could not with the stock printer. So here is my solution.

It reuses the screws from the hot end radiator, but they only work if you remove the washers.

It's designed 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.

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.

Please note, this is not compatible with the auto leveling sensor. If I get enough requests, I may figure something out. ;)

Print Settings

Printer:

Tronxy X3

Rafts: No

Supports:

No

Resolution: 0.15-0.25mm

Infill:

20%

Notes:

3 shells or outlines.

Print one in PLA and then use it to get to higher temps and then reprint in ABS, ASA, or PETG. The heating element wires get warm and will warp a PLA version, but so far, 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 o the shrouds.

Post-Printing

For PETG, I've been running the part cooling fans at 25% and they seem to work well.

How I Designed This

As usual, my gateway drug of choice is Onshape.

I started the design on my iPad and then switched to my desktop since I have a bit finer control with my mouse and a bit faster--but not as comfy as designing on the couch with my dog at my side.
