3D printed helping hands

I just added a cool new accessory to the Stickvise website.  It is a 3D printable helping hand system, tested and works great for holding wires / cables when soldering.  Here are a couple pictures of the fully assembled system.

This is a worthwhile upgrade even if you already have a third hand or helping hand setup because these stay with the vise, making it easier to move your project around.

Details:
 
Special quarter turn nuts attach to each socket as shown below.  With nuts installed, the socket cannot expand and the ball joint will not separate unexpectedly.  To disassemble, simply twist off the nut and the ball and socket pop apart fairly easily.

The arm ends with a special attachment designed to hold an off the shelf alligator clip, Mouser part number 835-501784.  To attach the clip, wrap one turn of electrical tape around the banana jack and press it into the end of the 3D printed holder.

Each arm mounts to a special Stickvise jaw plate that has two ball attachment points.
