TubeRig is a Blender addon that allows you to easily set the thickness of your Rig widgets. While Blender has a “Wire width” setting since version 4.2, this addon lets you to make your bone shapes even thicker and easier to select.
The addon takes your existing Custom Bone Shapes and wraps them in procedural geometry. No manual mesh editing is necessary.
The addon is simple to use: find its settings in N-Panel of 3d view, press the “Apply TubeRig” button, then set the Thickness value. To remove the thickness effect, press the Remove TubeRig button.
