I made this for a friends telescope set-up to enable him to attach little mirrors and adjust their angle.

Could also be used to mount a variety of components, cameras, speakers, etc.

I designed this to be clipped together but still stiff when connected. However, you may want to scale one of the parts up or down to suit your printer calibration.

Can be printed without support but I suggest a high infill to increase strength in the fingers and waist of the ball.

You can attach through the centre hole or either of the corner holes.
