I made this to connect my helping hands to my storage wall. This might not working for your hands, so print off the nut first to see if you can screw you hands in. After its screwed to the nut it can easily be pushed into the insert and removed as needed. Its friction fit, so you will need to push a little to get it in, and pull a little hard to remove it.
The author remixed this model.
This was made to insert into the honeycomb wall.
