All parts are 3D printed at 0,2mm layer height, 100% infill in Transparent PLA.
You can 3D print the parts in ABS or PLA.
There are 2 versions of this design. Version 1 with the assembly part integrated and Version 2 with the assembly part separated from the arm, for better 3D printing, that required very little amount of supports.
Hope you enjoy this 3D Design, made in Sketchup.
I also uploaded the skp files.
