I've bought myself a 3D printer half a year ago with the idea of printing custom parts for 1/24 scale models and been struggling since. I can't seem to properly setup 3D objects with a correct thickness so the print doesn't fail. I've spent countless hours trying to achieve the correct results, in multiple tools, using multiple plugins and so on. Currently struggling to add thickness to a rim and I followed the details provided within this thread but when I press E (in Edit mode) it simply duplicates the mesh selected, without any connection between the two. Any suggestion on how could I achieve a good result?
I know it's a lot to ask but maybe you could create a short video and post it on YouTube? That would be greatly appreciated, thank you in advance!
