This Axon Connector is by Berlin-based 1x1 Systems, a company that empowers local production of furniture. It's a 3D-printed connector that allows the user to quickly knock together a coat rack out of wooden rods.

The idea is that you use the company's online configurator to tell it how many rods you want to use (3-5), and the diameters available to you. Then it spits out the .stl file, for you to print the part on your own.

"It adjusts to various diameters of the legs, allowing it to fit almost any material users can find in their surroundings. It can be customized to fit between 3 and 5 legs and also changes the angles of the leg mounts within the connector based on the total dimensions of a configuration—all while maintaining the same height, wall thickness, and screw placement position."

The .stl files run €10 (USD $11) to €20 (USD $22), depending on configuration.
