So, I'm trying to print some older models from thingiverse and I have discovered that basically all the files I want to print have glaring flaws in them.

Internal free floating structures, connector pieces and holes that are the exact same size... So on and so forth...

Do I need to learn a software like CAD or Blender to fix these? I seem to be able to do some basic stuff in Orca Slicer but it honestly seems like as much of a pain to modify the parts there as it would be to use a real software.

Is there one that's easier? I think I messed around with SketchUp once upon a time.

I am worried this feels like opening a can of worms just so that I can make a thing that already exists in a dozen forms better.

Yes. Advise against doing what I did which is getting weirdly agile with modeling in the slicer at the cost of making cad software less desirable to learn. I finder Tinker cad pretty limiting and personally I can do more in slicer than I can with tinkercad. I do like Mattercontrol which is free, easier to use, and more powerful than tinkercad.

I find knoowingbthe basics helps.

I use blender. Its not perfect for 3d modeling. But I knew it a little to start. Also easy to set up on linux.

But honeatly learning its scale odds. (Defaults 1m to mm) boolean modifiers and 3d print tools. (Allow testing for real world models and extra faces.)

Really is all i need to modify stls and make my own sruff.

@Krauerking my opinion is no. For many things you can find a model on line. Much of the challenge can be getting the printer to work as you wish, so modelling might not be first on the to do list.

Good old Thingiverse. You'll get a great education in now not to design things for 3D printing wading through that slurry pit.

Yes, consider a 3D printer useless if you don't know how to use 3D modeling software.

May not be a popular opinion, but if you just want to fix shit like that, you can use Microsoft 3D Builder, it's super simple and pretty powerful.

Modifying existing meshes is difficult, especially more complex ones, I find that this makes it much easier to fix dumb shit or make simple modifications.

Is that like their replacement for 3D paint? I used that once to add a hole to a model?

It's insane that I feel like I can understand the rules of 3D printing just fine but need to potentially put hundreds of hours learning software to fix other models so I can do it past the easier fidget toys that seem to be designed by the modeling geniuses.

No, it's adjacent to 3D Paint. I never really liked 3D Paint actually.

For parametric modelling, that's super easy and you can get into it pretty quickly, but organic modelling is a whole different story and is what takes the hundreds of hours.

While I've messed around in Maya and 3DS Max, its so much more difficult than parametric and Modifying high poly models requires tons of ram and a beefy PC. I spent a month trying to bake a bump map onto a model so that I could 3D print it and 90% of the time the applications crashed, Maya, 3DS and Blender all crashed when trying to do it, and none of them could do it right either. I pretty much gave up on that.

Thanks that seems about right for my experiences but that seems like the info I need.

Oh my God the bastards at Microsoft killed the app!

I had used that before to fix files. It was great.

I can't seem to redownload it without jumping through hoops but know this was the right answer for none coder fixes. Sigh.

Wait, you can't downland it from their store at all anymore?

i've been dying to try an llm that can generate stls from natural speech
