This is a part cooling blower duct I made for my Maker select plus. It uses the existing 2 bolts that hold the rear electronics cover on. This part will replace the cover on the back. This part uses the upgraded blower type fan.

**Because this design mounts to the bent metal bracket on the back, it only seems to work for half the people that try it, unfortunately. It appears we all have slightly different bends on that part so this does not line up for everyone. I will be working on it further.....

On my Wanhao Duplicator i3 Plus is dosen't fit directly, are the idea that another "back plate" should be printed as well?

No it should replace the back plate the printer comes with, but I'm finding a some people are having problems with this design. Fits my printer and some others great. I will be redesigning soon to fix some of the problems you guys are having.

If interested stay tuned for a v2.

I'm not sure what too call the parts, but with "back plate" I did refereed to the plate which the smal PCB sits on and not the cover.

I will attach a picture of my "back plate" or "PCB holder" with measurements on.. I used my amazing Paint-skillz ;)

Wow your back plate makes this sit a lot different then mine does....

Maybe I'm just not experienced enough to be trying this design, but I can't seem to figure out how to get the internal supports out of the tubes so the air will blow through. I understand that S3D produces better supports that aren't as firmly attached to the model, but I don't seem to be having much luck with it--adhesion issues and such. Thoughts?

If your using Cura check the box that says supports from build platform only, it will work fine.

If you are using S3D you can generate automatic supports or do them manually. If you do automatic, it will place them where it thinks they should be, like inside the ducts. If you do them manually you can place the supports where you want. I used 8mm supports under the majority of where you need them and 4mm supports to fill in the gaps or in smaller places. If your having adhesion problems in S3D, under the supports tab you can tell it you want 1 or 2 base layers. That will make a solid base layer for the support to grow off, you could also increase the support infill percentage to make a more dense support.

Let me know if that helped at all.

Yeah, that helped a lot, as a matter of fact.

I've printed this model about 4 times now, and the latest one is going to be fit onto my printer this evening, if I can get to the hardware store to get a new machine screw or two bolt it on. (The printer only came with one of the two it should have, and the one it came with is likely too short to hold the duct in place.) I prefer the support setup in S3D--I can virtually build the model and delete any supports it tries to position inside the ducts. Unfortunately, I accidentally deleted a support under a corner of the plenum, resulting in a bit of air leakage there. Also, I missed a couple internal supports and had to knock them off with a screwdriver during printing. (Probably not a smart thing to do, but I got away with it this time

Printing with Cura, using the supports from build platform only option worked pretty well, except I tweaked the support type, changing from zigzag to triangles, and the triangular supports' grip on the material is rather tenacious.

All that aside, this is a pretty sweet looking fan duct, and I'm eager to get started using it. Thanks for the creative work and for your help getting it printed successfully.

Not a problem, and sorry to hear about not getting all the hardware with your printer..... If you can please post back and let me know how it fits and works for you.

Well, rats! I like this cooler a lot. Don't have a fan to run it yet, but I think the design is clever and well considered. I bolted it onto the shuttle, and the reach of the ducts is a little short of where I imagine I want it to be. Instead of sitting at either side of the nozzle, it's about 12 mm behind it; and it hangs a little too low as well, maybe 5-6 mm lower than the nozzle itself. Now, I have to be fair, this is a PowerSpec Bi3Plus, not a Maker Select, so it was a roll of the dice whether it would fit, so that's not a complaint by any means. I'm just disappointed that my machine isn't close enough that it would work for me.

Ill mod it for you if you can give me specs, don't worry ill make it work for you. I didn't know you had a PowerSpec. Dimensions must be different. I can make it for you.

You can help me make one for a PowerSpec.

i have a power spec as well, what orientation are you pingthing this on? all you need for this is to remove the back cover (the cooler has a cover built in) make sure support are on Print bed only and use the same screws of the back cover to mount the cooler.

if you need any help let me know

Edit: All Plus models are the same just a Rebrand from the Wanhao they are all 24v and build the same.

I did remove the back cover and replace it with the model. It fits perfectly. But that positions the outlets of the ducts a little too far back and too far down from the nozzle.When I get a chance in 10 hours or so, I'll post a photo, if I can take one that illustrates the issue. @kevinb22, I will be glad to give you whatever dimensions are needed to develop a model that fits my printer, if you're open to doing so. I don't want to put you in a position of feeling obligated to make a ton of one-off mods for each user with a slightly different configuration, though.

You can't tell from either of these photos, but it appears that the plate onto which the back cover--or this model--gets bolted is about 10 degrees away from plumb. I can't say for sure, but maybe if it were bent back to nearly plumb, the ducts would be at the right z-height. I'm confident they'd still be short of being centered on the nozzle.

I'm not thrilled about bending that particular bit of metal, but I wonder if I could shave the nylon spacer on the bolt that holds that assembly onto the deposition head, thereby rotating the plate closer to plumb. Thoughts on that?

Ill make it work for you. If you back plate is bent, then that would bring it to the right height it looks like. But no point in bending your plate, if I need to make adjustments anyway Ill just raise them up. Ill just estimate from your photos and we can go from there. Its going to be all guess work for me, but I'm up for it. It looks like it has to move a touch to the right for you as well. I don't get why JuniorGamingTime lined up perfect on his powerspec and yours is way off though.

I don't know that the back plate is bent--it may just be that production values are sufficiently sloppy that you get a wide variation of geometries that still manage to print well enough for a sub-$500 device.

In any case, the mods you made resulted in what looks like a perfect fit. I'm still waiting on my radial fan, so I made an adapter to use the stock fan with your cooler. Left it half printed when I left for work this morning, so I'm hoping to give it a try this evening. I understand the stock fan is kind of underpowered, so I'm not going to print anything important till I get a radial fan, but this is definitely looking like a real hit. Thanks for everything, Kevin!

Awesome glad I was able to get it working for you

You can also generate automatic supports and the remove the ones you don't want.

This Cooler honestly fits Great, doing a few test at the moment and the mone..... i mean models are looking really nice.
ill update the post if i have any issues. :3
