Thank you for including the source files! It's so much easier to make specific tweaks that way - vertex editing is such a pain. I'm looking forward to finishing the print.

Printed in Prusament PCCF. The organic supports took less effort than expected to come out of the air ducts :)
Printed in Extrudr GreenTec Pro. Looks very good, but haven't installed it yet...
Print from PC-Blend. Works fine after a short test. The cooling legs are moving very close the printing object - I have to be careful when the object starts to twist above the printed plane. (edited)
Great design!
Printed in ABS on the Bambu.
Fits perfect and cooling improved a lot.
Great remix! There are some nuances to installing this duct, such as shaving down the bed screws, using spacers on x axis etc, but it's very much worth it!
Between this duct and the LDO ball bearing 5015 fan I installed, my Mini has part cooling for days now! lol
For anyone about to make this duct, I'd definitely use their 90 deg bed cable cover for more clearance. If not, you'll have the duct running into the stock cover. Even with the 90 deg cover, my fan duct still barely grazes (by about 1mm) it with the bed fully forward. So that's something I'll have to keep in mind when slicing future models. Thanks for remixing it!
@Griff Hey thanks for the feedback!
Can you link me to the fan you are using?
@Waschtl No problem. Here's the link to where I bought the fan. If you are USA based, this company is great to deal with. They tend to have some of the better prices on E3D and Prusa items that I've found. Even better is that they're a small (husband and wife) business that does a nice job with their website and attention to detail. https://www.partsbuilt.com/blower-fan-for-print-cooling-5-volt-dual-ball-bearing-5015-mk3-mk3s-mini/
That fan will work with both a MK3S and a Mini. Just be aware that if you use it on a MK3S, you'll probably have to disable the fan check in the menu. The reason is because the fan spins faster than the stock Prusa one, so the printer can think there's a fan error, which causes the print to fail. I have not installed one on my MK3S yet, so I can't confirm this. So far, it has worked great on my Mini with no issues. Thanks again and Happy New Year!

Hey, thanks for your work -- before I print this, are those space clips still needed?
@strugo_272543 Hey, I would still recommend printing these spacers with at least 1.5mm of thickness to avoid the air duct crashing into the X-assembly where the motor is. You can make them thicker for X-axis offset calibration. Mine are like 4mm thick
Thank you for the good model.
I used it on Red Lizerd, but it looks better than the others.
