This is a multi-way connector for the Tentacle System.

• It has a ball so it can be a base
• It has a cup so it can be a holder
• It has a thin slot and retaining flange so it can be attached to the back of a binder clip.
• It has a long dovetail pin so a binder clip can be attached to the side of this connector.
• It has a hole in the middle so things can be hung from it or tied to it

You can use this lots of different ways.

• Attach a binder clip to something and this connector provides a ball so it can be a Tentacle Base.
• Attach this connector to any other Tentacle System base and this provides a binder clip to as a holder.
• Attach this connector to another similar connector to add more cups and balls for more connections

The Tentacle System allows you to create ad hoc stands and holders using a variety of connectors and holders. So, all of the other Tentacle System parts can be use with this to create unique stands and holders.

It prints in three pieces, with supports. The pieces can be oriented however you wish, except that the ball and cup are always at 90º to each other. The pair can be oriented however you like. You will probably need to superglue them together to secure them.
