Fits perfectly

@Rodnock_2933338 Thank you for your feedback! Glad it works for you.
Workes very well with the LM2596S chassis. The noctua is a 15mm one i had left over. Thank you very much !
In hindsight i would modify the grill a little in the slicer fill it below the converter chassis.
🚧 One other thing, the fan connector was labeled wrong on my mainboard. The silkscreen has the wrong polarity on it. Maybe check this with a multimeter beforehand. (edited)
@eickeler_247213 Thank you for the info and for posting your make!
@LiefErikson_2248993 Thanks for posting your make!
Had issues with "non-manifold edges" in orcaslicer, fixed it using blender "remesh" modifier
@lumetorm_2342269 Thanks for your feedback! Glad it worked for you.
Looks fine, everything fits, I will install it once I get better screws for the fan. A round head screw won't fit under the convertor.
@Voenie_1706721 Thanks for your comment! Looks like a good print.
@Combass_1908086 Thanks for posting your make.
@JayReed_1598763 You’re very welcome! Glad it worked for you.
Nice model. Printed in PETG.
Fan grill from https://www.printables.com/model/403384-hex-fan-grill-for-92mm-fan
and LM2596S housing from https://www.printables.com/model/408716-gehause-lm2596s-dc-dc/comments (edited)
@PhantomAura_1179965 I used the housing for the LM2596S from https://www.printables.com/model/408716-gehause-lm2596s-dc-dc and attached it with 2 M3*4 screws (+nuts and washers).
But that's a good idea, both models could be remixed to cover less intake and not have to use screws.
@Aferac_1360715 awesome, I hadnt gotten around to making or finding a housing, this looks perfect!
I followed the lead of @alfarofilms_1593387 as I also didn't want to solder anything (and because I couldn't find a converter with the same hole configuration as the model (and I didn't want to mess around with modeling). I didn't want to have to futz with the screw on the converter to control fan speed so i fount a potentiometer with a PWM fan connector on Amazon.
I have the buck converter connected to the potentiometer, which is connected to a 3 way fan splitter: One to the PSU fan, one to the Mobo fan (I also installed https://www.printables.com/model/565011-sovol-sv06sv06-plus-ultimate-motherboard-fan-mod-9), and one to the exhaust fan for the enclosure for my printer. The unfortunately thing about this potentiometer is that ther isn't any mounting holes, and it's too deep to have mounted through the converter screw hole, So I... utilized the plastic case that it shipped in.
This was one of my first prints, and you can see my z-offset wasn't quite honed in yet, but function of form and all that.
Pairs great with https://www.printables.com/model/403384-hex-fan-grill-for-92mm-fan/comments
@DupsMcKracke_1733828 Great work! Thanks for posting your make and info for others that don't want to solder. Totally agree, function over form, and yours definitely fits that bill.
Didn't want to solder, so I got a different board. Still worked out like a charm 😎😎😎 now I just need to make a cover for it.
@x121887x_257215 not sure if you ever got this answer, but I found this one: https://www.amazon.com/gp/product/B08977C9YM/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 and it works great so far.
@x121887x_257215 My apologies, I just noticed this!
This is what I used:
