DUST EXTRACTION BALL JOINT

I designed this to fit onto my dust extractor shown. This for sanding and my pens nothing more it works good for what I designed it for. If you want the 3FD file let me know.
The 2 halves are joined by a smear of super glue on the outer edge all round and clamped till dry. This was a first so may make bigger to accommodate screws.
You need to clean any zits off the ball and socket to get good movement.
