A more moderate version of my 4xL ball joint. Designed with Bionicles in mind, but this can be a useful part for any designs that accept an axle or pin. This one is double the size of a standard Technic ball joint.

I recommend printing with a brim to reduce warping on the corners. I have had a lot of trouble with that. This should print fine without supports.
