Hello, Everyone!
I have just printed the Art1BodyP3 part in a splitting ;way. The objective is print without supports and in a cleaner way.
I edited the STL file in OpenSCAD like you can see in the attached images.
I used 2 M2 x 12 cap screw with a nut to join the parts. I show some images of the final result
The STL files are posted in my GitHub ;fork of Thor page: ;https://github.com/wgaonar/Thor
