I needed some strong magnetic hooks for a hanging garden I'm working on and I've been meaning to try out TinkerCAD - I am pleasantly surprised, simple yet capable environment and the learning curve is basically null. I am mostly used to working in Solidworks but I'm trying to make the move to various open source or free CAD platforms.. So far, TinkerCAD's environment has been the easiest to get started making easily 3D printable models. I'll be working on a support-free thread feature once I've got some spare time to learn more about the API.
designed to fit these magnets, this object should print easily on any machine. I'm actually really pleased with how nicely the prints turned out - TinkerCAD's STL file generator is great, I had no idea!
It's my go to tool, I use it for must of my prints, both originals and when I cut-up thingiverse items, to fit my small 10cm^3 build volume.
It has yet to let me down.
I'm glad you are pleased with your experience. I rather enjoy using Tinkercad myself. Most of my designs are made on Tinkercad.
