Quoted from Sleal16:Yeah, good idea there. Sucks (bot not really) for games that save on system resources, it'll use low polygon models but masked by skin/texture renderings. Looks perfectly fine in game but cant really extract it for direct model use
Subdivide the surfaces and you should get a smoother model.
I got tired of the flipper fade on my LOTR. Tried the high strength coils but didn't like them so I put back in the stock coils and made a fan mount that cools the coil with a 12V fan.

IMG_3217 (resized).jpgPinball v16 (resized).pngQuoted from latenite04:Did you need longer mounting screws for this or did you use the stock ones?
Actually, I don't remember but I'm pretty sure they are stock. I would have thrown the old ones in the cash box I don't' see them in there.
Quoted from Mr_Tantrum:In what orientation did you print these (I see you noted supports are required)?
I printed it grill side on the bed. The supports are to hold up the screw side up top. Supports don't have to be too aggressive since it's just a horizontal piece. You want them to snap off easily. I printed at 0.3mm layer height.
The STL on ThingiVerse is oriented weird because that's how Fusion360 exported it. I'll try and rotate it so it's the correct orientation for printing.

Looks great. I can add it to ThingiVerse is you send it to me.
Quoted from Pin_Fandango:I need to learn how to do this asap. Fusion360 is a lot of fun.
I like what you did with the ventilation but i was wondering if this is needed at all, do you think the fan can be held with just two screws? Then you would not need the grid at all…
This is definitely a mod on my list!!!
Learn by doing! I was "forced" to learn Fusion360 because I was asked to make a project for the International Space Station. It was either learn or pass up said project.
As far as the grid goes. It's probably not needed. But it does prevent accidental touching of the fan if you were to stick your hand in there with the power on.
Quoted from Mr_Tantrum:What I did was pretty simple in Tinkercad since I didn’t have source file. Just import STL, overlay cut shapes to remove existing grid and merge, create/import hex pattern, size and position accordingly, remove any excess material, fill any gaps, merge and export. Sounds like a lot, but I literally spent maybe 5 minutes doing it. Also, I could easily remove the grid altogether (see attached image) just leaving the open square with the four mounting positions remaining. Personally, I recommend something there just to prevent accidental damage to the fan from fingers, tools, etc., but certainly not required.
In looking at the model, I would print at 100% infill or at least add infill modifiers in the slicer around the six screw holes and do 100% infill there.
If you would like the model this way, I'm happy to send STL to creator to post with his other files on Thingiverse if he so chooses.

Yeah, we can add that as well.

I modeled the fan to give an idea of the air flow through the grid. I oriented it to push air over the coil. Although I understand there is reason to pull air over the coil as well.

The parts are on the Thingiverse page:

But here's a direct link to the fans:

Quoted from latenite04:Thanks for this. I changed out the grid to be circles so I could print it on its side with no support. I just started a test print.
[quoted image]
Very clever.
Quoted from Mr_Tantrum:Probably not an issue for this application, but this print orientation produces a structurally weaker part at the expense of saving a little plastic and time (the cutout shapes will not be as precise either). Also, you probably will want to modify the 90 degree overhang on the back support when printing in this orientation so that a fairly long bridge is not required.
[quoted image]
I modified the back spine to be 45 degrees and eliminate overhang. I also rotated the grid so everything it at a 45-degree angle so supports shouldn't be needed (mostly) when side printing. But I didn't see a huge savings in print time.
square1 (resized).pngQuoted from gandamack:Is getting into 3d printing (a hobby unto itself) difficult. Is it difficult to learn? How much is a decent set-up? Thanks
It's not hard to learn. If you can handle a pinball machine, then you are probably able handle printer maintenance and modding. You can start with premade stuff off of places like ThingiVerse then learn how to make your own with the various 3D CAD products. I use Fusion360 and Blender but everyone has their own preferences. YouTube is usually a good source for tutorials on the various products. When I have an idea, usually someone has made something similar on YouTube and I just follow their instructions and tweak until I'm happy.
If you have a local Makerspace then they almost certainly have a 3D printer you can try out to learn the basics. Even some libraries have them now.
