I've used TinkerCAD (https://www.tinkercad.com/) and was able to easily model objects for 3D printing, despite having no prior experience in 3D modeling. However it needs to be connected to the internet to work, which is not always available at my location. At minimum, I need an ability to create solid shapes and holes, and with resize, align and rotate options.
Is there an equivalent program that's free, with a similar intuitive interface as TinkerCAD, and works completely offline?
I suspect there may be fewer answers than we expect. Personally free software wise I like FreeCAD but it is not similar to the simple shapes of tinkercad at all and not intuitive.
I did know someone who used something from https://www.xyzprinting.com that was very similar to the tinkercad stuff, but eventually ran into limitations and switched to more advanced software anyway.
From trying out several alternatives (Fusion 360, Wings 3D, Blender, and others), the closest free offline equivalent to TinkerCAD turned out to be OpenSCAD.
It has nowhere near the same level of intuition, but based on info from two tutorials ("OpenSCAD Tutorial - Beginners Quickstart", "OpenSCAD - Model a Bearing in less than ten minutes."), OpenSCAD was able to fulfill the minimum requirements that were needed from TinkerCAD most quickly, i.e.,"...ability to create solid shapes and holes, and with resize, align and rotate options"
