I cannot see how 3 out of the 4 were printed without supports. Can you elaborate on that a bit?

Perhaps the magic lies in my use of ABS. I've attached a photo of this printed wizardry. Maybe printing layers from inside out will help you or a layer fan.

Thanks for the reply and pic! I would be interested in your speed settings and wall (XY) settings.... but I know this was quite some time ago so no worries if you don't remember. Great work BTW! A scaled up (and modified) version could work for speaker mounts too!

The ball joint gets pretty weak at the attachment point.

Any chance for one attached straight to the bracket?

I printed this, and trying to figure out how it works... because the knob thread (cogwheel like) has a larger diameter than the ball... so it can't clamp it down? If not the spinning knob, what is supposed to hold the ball down?


The ball goes into a socket. When the nut is tightened onto socket the fingers of the socket compress onto ball to increase resistance to movement.

I wonder if this would hold well with PLA?

I have printed this 3 times and the socket joint (where the ball goes in) snaps immediately. it seems too weak, even when printed at 0.2mm and 60% infill.
Printed in PLA.
