For the addition of a 40mm cooling fan to your TronXY X1 3D printer. This design is intended to take advantage of the existing screw to the right of the hotend assembly (see picture), with a larger hole in the front of the shroud so you can tighten the screw with the included screw driver that originally came with your TronXY X1 kit.

I have tried making this three times. Slic3r seems to understand the STL but no matter what I do to the settings the curved back of the shroud doesn't print. I have managed to get the last centimeter or so to print at the top of the print but from the fan mount side up that whole side of the model isn't printing. Sorry, moving on to some other design.

I get a lot of extra noise from the shroud rattling around. This is probably because its attached with only one screw, I don't know what the solution to this is though

Are you using the screw that the printer normally used in that location? If not, it could be too long. A single screw should have no issue securing <20 grams of mass if it's tightened all the way down.
Other than that I dunno.

I'm thinking of putting a piece of this on each side of the extruder. it's possible ?

I don't have the printer anymore, but I think I remember it getting in the way of the limit switch or perhaps the frame as it homed.

This design is not optimal. Because it is directed at the nozzle, air from the fan cools the hot end too much (about 13 degree celsius drop in temperature for mine) causing the nozzle to stop extruding.

I recommend modifying the design/ try other models or adjusting the fan speed (25% max speed works fine for me so far) to prevent the above mentioned problems.

This design has been used on several TronXY X1s for the past year, fan speeds all at 100% and no temperature drops or issues printing. A standard run of the mill 40mmx10mm fan should not be capable of generating enough airflow to cause a temperature drop at your nozzle significant enough that the heater cannot compensate for it. I'd suggest checking out your thermistor and heater cartridge placement to ensure they are making good contact.

I don't own a tronxy x1 but a friend is buying one. Just wondering what side effect this mod has since you are blocking the vent to the existing fan that keeps the heat break cool?

Pleased to see the fan shroud, but Im wondering why no-one has yet styled it with a 360deg 'skirt' to direct all airflow around the model. Everyone seems to be blowing air from only 1-2 sides. I did notice that there was quite a dramatic improvement in print quality on the side that was cooled fastest with the original 1-direction fan. "I guess I'll try to adapt it myself" said the Little Red Hen" - Thanks for the headstart : )
