C-3PO arm greeblies and bits

thingiverse

These are the decorative pieces for the arm models I've submitted. The elbow attachment has a dimple to match the locating nub on the elbow collar. The slider parts fit into flat spots on the arm and have tracks for sliders that I haven't fully designed yet. Once the slider is installed, the open end will need to be plugged with a small piece that I'll post when I create it. The greeblies are just glued on by eye, as their positions aren't critical for function. Better late than never: I promised at some point to add some detail about the piece I intended for the piston connector. I just attached a snapshot of the model and a PDF drawing. The piece is made from some extruded aluminum I bought. It's a 1"x1" 'L' shape that is 1/16" thick. I printed out the drawing, cut out the profile in actual size and then used a hacksaw and files to shape it to the paper. Once it's all fitted, I just expoxied it in place.
