any info on layer height, infill, material, etc?

No setting in particular. A layer height of 0.25mm should be just fine with an infill of 35% or so. Material is up to you, PLA is just fine for ease of printing.

Please make for 140 mm

Thanks Inertpyro, this is beautiful, a work of art! I sure wish 120mm was big enough for my application (which unfortunately is 8 inches, about 200mm).

The little pegs on the rig that are supposed to slide into the grooves of the fins don't seem to be tall enough to catch :(

Thanks for the design! It printed easily and well. I made some pins under 'remixes' to replace the M3 bolts and washers so the entire door can be 3D printed (not including fasteners to the fan body) https://www.thingiverse.com/thing:2455186.

After installation into the corner of my temp cardboard enclosure, I didn't make allowances for the 'open' clearance required or how awkward it is to open or close deep inside a large enclosure. I'll be replacing this aperture door with a simple flap and flexible filament clasp as I don't need the variable opening aperture in a PLA (fully open) or ABS (fully closed) fan hole opening.

I'll certainly be using this or something equally attractive in a permanent enclosure or location with front clearance issues.

Can anyone tell me how big this thing is when fully open? I'm trying to determine where I want to cut the holes in my enclosure, but don't want to have clearance issues.....

Any way to attach a hose to this? This would be perfect if it had a hose adapter to blow fumes away from the house :<

Nice design, well deffs print

Would you design a 80mm version for us in need? :)

Sorry for the delay. If you are still interested I have uploaded a 80mm version.

Definitely still interested! Thanks!

Could this not just be scaled down for 80cm? Not sure by how much. I am too new to all this.

It would not scale down well since the holes for the screws would also shrink. Unfortunately I haven't had time to design a 80mm version.

Great design. I too would be very interested to see and make an 80mm. I have plenty of 80mm fans and will be making an enclosure shortly. thanks

Nice design, I need something like this for my enclosure for the same reason, silly question: does the 5 iris parts move together or individually? And yeah motorizing it would be neat, much easier if the 5 parts move together.

They all move together by turning the ring.

Awesome,.. would it be possible to add a 80mm version? Tried simply resizing the STL but didn´t work, the grooves for the blades and the corresponding "pins" in the Ring didn´t really match.

Sorry for the delay. If you are still interested I have uploaded a 80mm version.

Yes, I dont think it would scale well. I am away this week, but when I get back home I can work on a 80mm version. It might have to be a 4 blade design, because I think the blades might end up being too small, but I will see.

Did you have a chance to look at a 80mm version it yet? I would try to design it myself, but i have some troubles getting your current design in 123D design and then the next issue would be how to go about the redesign/scaling. I have no idea how to approach that problem either.

I was hoping to closely adapty your design because i absolutely love it and i can not find anything alike!

Sorry for the delay. If you are still interested I have uploaded a 80mm version.

Wow, that sounds like a lot of work, I would surely appreciate it, since your design is really neat and beautiful. I

Thanks for the link. I messaged you on IRC about this. I suggest maybe adding some keywords such as fan vent cover since that's what I was trying to look it up as. Not sure too many people would try "aperture door" :)

I will do that. Thanks!

Any chance to motorize this? I mean Like add servo close to it? :)

I have thought about this. Its certainly something to consider. Might be a good little project for this winter.

it looks like I was able to get up math to calculate some dimensions for moving this with servo, let's assume that the servo got angle of movement around 90 degrees ( +- 45) and you want to move this +-30. so if you put one joint for arm on "top_ring" and second joint on the end of the arm of the servo, which axis is let's say 90mm from the center ofthe doors, you should be able to move with the servo +-45 degrees so that the doors move +- 30 degrees accordly.... you just have to know the length of the arm connecting the two joints and length of the arm on the servo.
...
and after some math I put some equations together in python it worked out values, that simulated in scad showed sensible results :) :
from math import *

alfa1 = radians(45)
alfa2 = radians(30)
r2 = 55
x = 90

c1 = cos(alfa2)r2
c2 = cos(-alfa2)
r2
d1 = sin(alfa2)r2 + x
d2 = sin(-alfa2)
r2 + x

f = pow(cos(alfa1), 2) + pow(sin(alfa1), 2) - pow(cos(-alfa1), 2) - pow(sin(-alfa1), 2) # always zero
g = 2cos(alfa1)c1 + 2sin(alfa1)d1 - 2cos(-alfa1)c2 - 2sin(-alfa1)d2
h = pow(c1, 2) + pow(d1, 2) - pow(c2, 2) - pow(d2, 2)

r*g + h = 0

r = -h/g

r = abs(r)

l = sqrt( pow(a1-c1, 2) + pow(b1-d1, 2) )

oh, sorry, main point: result is that for servou with axis 90mm from center of doors and joint on the doors on radius of 55 on the doors, you should:

create servo arm with joint 38.8909 mm from servo axis and connect that two joints with arm 92.2240mm long.

only downside is that when the mechanism is in the middle (both angles 0, if we count that we go +-angle) two "arms" which hold the joints should be parallel...

Interesting. Thanks for doing the math. I think I have a couple of servos laying around I can use to test with.

How did it go with the servos?

I never got around to trying out servos. I plan on building a new enclosure in the future so I might get around to it then.
