content: HiI am a total Noob and finally want use Blender to create my First 3D Printing Part. Its "just" an Adapter for my Pc to put affordable 80, 120,... mm Fans on the Case who is design for 50mm one () and maybe prepare everything to put an "old" Consumer Home Air Filter (who I blow out with Compressed Air to get rid of the Dust and so) on top to clean the Air while the Pc anyway run.Hopefully the Filter suppress some Sound to.Well for that I must know how to Model something in Blender. I never use any of that. Well I theoretically know how theoretic how the work. My 3D Printer need some work and I finanlly want use them...Thanks

content: I suggest looking at the official tutorials:https://www.blender.org/support/tutorials/I personally find Blender pretty cumbersome - I guess I don't have the patience to learn its quirks, at least for now. I use OpenSCAD for modeling 3D parts, and it exports to STL, which can be 3D printed directly.https://openscad.org/May not be your thing, but just mentioning something that works for me.

content: I exclusively use Blender for all of my 3d modelling and 3d printing. Caveats:* I came from the polyagonal world of video game 3d modelling, not CSG based mechanical CAD modelling. They're different processes with different mindsets.* For 3d printing your models need to be "watertight" with no gaps. In vertex edit mode the Select -> Select all by trait -> Non-manifold tool is very useful for finding where there are gaps in your model's polygonal skin.* There is a 3d printing addon for blender that tries to automate this, it sometimes helps* If you fail to make your models watertight and free of impossible interior faces/edges/verts: your slicer will get unhappy and try to auto-fix your model. Sometimes this works, other times your model ends up full of holes and missing pieces.* A lot of the tools in blender are NOT focussed on watertight models, instead it's very easy to get fiddly models with lots of holes and impossible interior meshes. The program will not protect you, you have to learn what works and what doesn't.* The 3d boolean tools in blender (eg to merge multiple "solid" sealed objects) are a bit fiddly and require you to be imprecise. They don't like it when vertices and edges/faces of the two objects line up, so you have to move things a tiny distance away from each other before combining, etc.I have no idea how this compares to the problems you face in other styles of modelling software. It works for me, I've made lots of precise and complex mechanical parts, but it won't be everyone's cup of tea.
